COMPANY OVERVIEW

Polymer Pavements, also known as Polyroads, has its head office in Johannesburg, South Africa and is represented in eighteen countries on four continents. The company’s main focus is on the mining and on infrastructure projects in developing countries. These countries include Australia, Brazil, India, most of Africa, Colombia, Uruguay, Peru, Middle East and Chile. Polyroads manufactures and develops environmentally friendly Smart Materials for road construction, dust control, barrier liners and spray-on geoliners for dams. These Smart Materials includes in-situ material binders, soil modifiers, asphalt modifiers and elastomeric mortar admixtures.

Smart Materials challenges the core of conventional road construction and design, by bringing in unprecedented resilient modulus flexibility, which is required for Mechanistic-Empirical (ME) road designs. Smart Materials, reduces the number of supporting aggregate layers for cement modified/stabilized flexible and rigid road designs, and thereby substantially reducing construction costs.

During the past 70 years, a number of advanced countries have been researching and developing various polymeric admixtures in modified concrete mortars. Today, the USA, Germany, Japan have Standard Specifications for polymer modified mortars and concretes. However, in general the construction industry has been pedestrian in adopting technology.

Initially Polyroads developed products exclusively to address dust suppression on mines. However, over the years the product range has broadened substantially, with the products being readily adopted in the private and governmental sectors.

HEALTH, SAFETY & ENVIRONMENT The high level principles governing our operations are cascaded from Polyroads’ corporate organization through the regions and countries in which we operate. Managers of all functions and levels integrate health, safety and the environment into their activities and encourage a responsible safety culture. This forms part of a regular goal setting process and management evaluation. Polyroads is committed to the development and promotion of products, processes and services, which reduces waste. We encourage recycling and the adoption of environmentally responsible policies and practices throughout our individual operations to minimise any environmental impact. Polyroads has positioned itself as a company that provides solutions to the road construction and mining industry that have measurable environmentally benefits. These measurable are directly targeted at reduction in:

REDUCTION IN CARBON EMISSION

Conventional road construction and maintenance is a major contributor to global warming. SoilTech

polymers releases the equivalent of 2.7% of the amount of Carbon (CO2) into the air, in comparison to the equivalent concrete stabilized road projects.

AGGREGATE REDUCTION The consumption of virgin quarry aggregate utilized in road construction layer-works is simply not sustainable. Unsightly quarry craters, pock-mark the landscape and cannot be rehabilitated effectively. Smart Materials from Polyroads allows the use of in-situ discarded materials to be used in supporting layer works of roads. WATER REDUCTION - ROAD CONSTRUCTION & MAINTENANCE REDUCTION IN WATER USEAGE Conventional road construction and maintenance is a major user of water. The amount of water utilized for compaction of layered works in roads, maintenance of gravel roads and dust suppression in the mining environment is phenomenal and unsustainable

TAILINGS – REDUCTION IN DUST & ACID LEACHING Waste from gold mines constitutes the largest single source of waste and pollution in South Africa and there is wide acceptance that Acid Mine Drainage (AMD) is responsible for the most costly environmental and socio-economic impacts. BARRIER LINERS Polyroads offers an unprecedented range of cost effective barrier liners. Polyroad’s engineers are in touch

with the Department of Environmental Affairs in S.A., regarding the latest legislation pertaining to the

National Environmental Management Act, 2005. (Act No 59 of 2008)

SoilTech Mk. III Stabilizer

SoilTech Mk. III , a third generation polymer binder and is the flagship product of the company. It is a road stabilization agent specifically designed for mine haul-road stabilization, where excessive loading occurs and where all-weather roads are required. This technology is now used in commercial road design. SoilTech Mk. III has been extensively utilized in base and sub-base stabilization using in-situ materials, throughout the developing world, SoilTech stabilizing polymers are elastomers, which gain strength from mechanical compaction and do not become brittle when cured. The elastomer is able to flex under load and unlike cement stabilization, will not crack under excessive loading – one aspect in reducing layer work in design phases

SoilTech MK III stabilizers have been purposely designed to penetrate through the road’s base layer, into the sub-base layer, via capillary action. This sub-base strengthening process is of significant importance as we are not only stabilizing the road’s base layer, but also creating a semi-bound sub-base. From a road design perspective, a strengthened sub-base may negate the need for further layer-works. SoilTech, in many instances, transforms insitu materials that would normally be classified as unusable or waste materials, into suitably modified aggregates, for use in base and sub-base layer construction. With SoilTech Smart Road Materials (SRM), one can;

• Reduce the consumption of quarry aggregate in conventional construction • in-situ materials can be used • Speed up construction time • Reduce construction costs • Dramatically reduce CO2 emissions • Reduced maintenance – as long as the asphalt wearing course layer is maintained, the

structural integrity of the road will be preserved, with the road pavement remaining rut-free and eliminating the need for base or sub-base maintenance.

Smart Road Materials are technological advancements in polymer technology that drives our innovation in new construction methodologies.

A BRIEF HISTORY OF SOUTH AFRICAN POLYMER ROAD STABILIZATION 1. Since 1930 numerous companies and universities have been experimenting with various

alternatives for road stabilization products, as a substitute or replacement to conventional cement road stabilization.

2. In South Africa in 1983 the Transvaal Provincial Administration (Zadzick, 1983) first carried out

a practical road trial using polymers. The unsealed road displayed zero potholes after four months, whereas the untreated road showed numerous potholes.

3. In 1989 a polymer stabilized road was constructed in Sodwana Bay, KwazuluNatal, South

Africa. After four months various tests were performed and CBR and UCS results showed a strength increase of approximately 300% over the untreated roads.

4. South Africa 1996, a parking lot was stabilized in Marian ridge, Kwazulu Natal using polymers.

After 18 months of use the parking lot had a surface which was free of distortions, despite the trafficking and the more than 1 500 mm of rainfall to which it had been subjected.

5. Mozambique, 1997 various sections of a road was built in Mozambique, using polymers. All of

the treated 3 X 200 m copolymer containing sections were in good condition after 12 months. The 200 m section without an extra wearing surface showed the familiar distortion free surface of previous copolymer roads and was in contrast to the badly rutted and rock-strewn condition of the adjacent control sections after only four months of trafficking

6. South Africa 1997, the CSIR (Jones 1997) completed a battery of tests on 12 different

Gauteng gravel roads, using polymers. The four roads that had hard, compacted surfaces at the time of spraying the copolymer

emulsion six months previously, had excellent surfaces despite having been subjected to trafficking and over 100 mm of rain. In addition to maintaining an acceptable riding quality and reducing gravel loss in dry conditions, the copolymer treatment was also observed to reduce slipperiness in wet conditions (Jones, 1997). On the sections of those roads where the grader had deposited thick layers (more than 10 mm) of loose material, prior to spraying, the binding performance was significantly reduced.

SMART MATERIAL TECHNOLOGY FOR ROAD CONSTRUCTION POLYMERS – ROAD DESIGN

When completing pavement rehabilitation design, an engineer is typically faced with a wide array of test parameters and condition indicators. These parameters can be quantitative or qualitative, subjectively or objectively determined, and the sample sizes for different indicator types may vary significantly. For example, for a specific pavement layer within a uniform design section, an engineer may be faced with various parameters such as:

• Dynamic Cone Penetrometer (DCP) tests

• Falling Weight Deflectometer (FWD) deflections • Material descriptions and samples from test pits, together with standard materials

test results, including Plasticity Index (PI), grading, California Bearing Ratio (CBR), moisture content and density

• A subjective visual assessment with a description of observed distresses • Semi-subjectively determined back calculated stiffnesses from FWD tests • A general description of the material type from historical records, and

• A general description of the history and past performance of the pavement.

Based on this data, the engineer has to derive the key assumptions needed to drive the rehabilitation design. The synthesis of the information to arrive at design assumptions is one of the most important and difficult parts of the design process. Apart from basic analytical skill, it also requires considerable experience and knowledge of the main drivers of material behaviour (especially Smart Material stabilization). It is thus not surprising that engineers often fail to reach a consistent conclusion regarding pavement designs. This applies even more so to an ill-defined numerical parameter, like resilient modulus, which is needed for Mechanistic-Empirical (ME) design calculations. Engineers are expected to think out of the box and to research, engineer and create solutions to the diverse materials and challenges they come across in the developing world.

These polymer advantages, addresses the pivotal factors influencing road construction costs. SoilTech stabilized roads, should be at least 30% more cost effective than conventional road designs. Smart Materials from Polyroads, have been used to build roads in the most diverse conditions imaginable. These include roads constructed in; o Democratic Republic of Congo – using insitu soils o India – using insitu materials o Egypt – desert sand o Dubai – insitu materials o Mozambique – insitu materials o Colombia – insitu materials o Zanzibar – using island material (coral)

MATERIALS

Materials play a fundamental role in pavement engineering. Most of the materials used are bulk materials i.e. produced or available in large quantities. The vast majority of materials that are used for road construction can be categorised into 3 fundamental types:

• Granular or unbound materials (whether natural gravels or crushed rock), • Cemented materials (whether concrete or light cemented gravels), and • Bituminous (whether hot mix asphalt or surface seals).

An understanding of fundamental material behaviour is necessary before performance models can be developed for pavement materials. There are three fundamental types of material behaviour that are relevant to the understanding of road building materials, namely:

• Elasticity, • Plasticity, and • Viscosity

There are very few road building materials that follow one discrete mode of material behaviour. The behavioural types often need to be combined to model material behaviour more accurately, as shown in the examples below:

• Elastic material behaviour (cement/concrete) • Elasto-plastic material behaviour (granular materials) • Visco-elastic material behaviour (bituminous materials), and • Visco-elasto-plastic material behaviour (asphalt)

STRESSES AND STRAINS By definition, linear elastic behaviour implies that the relationship between stress and strain is linear. The point at which this relationship deviates from the linear form for a specific material, is called the elastic limit. If loading is removed before the elastic limit is reached, the strain is recoverable or elastic i.e. the relationship returns to the origin. If loading continues beyond the elastic limit, some materials experience a reduction in stiffness up to the yield limit. The maximum stress that a material can withstand is also known as a yield stress. This is a measure of the material’s strength (either compressive or tensile, depending on the nature of the stress).

Up to this point, strain has only been considered in one direction. The real-life situation in a road pavement is more complex, however, with stress distributed in three dimensions. In order to understand how three dimensional strain occurs in a material as a result of three dimensional stresses, we need to know the Poisson’s Ratio (ν) of that material. The ratio of resultant strain perpendicular to an applied stress relative to the strain in the direction of the stress, is the Poisson’s Ratio of that material.

RESILIENT AND ELASTIC MODULUS SOILTECH MK. III ELASTOMERIC BINDER The Resilient Modulus (MR) is a measure of subgrade material stiffness. A material’s resilient modulus is actually an estimate of its modulus of elasticity (E). While the modulus of elasticity is stress divided by strain for a slowly applied load, resilient modulus is stress divided by strain for rapidly applied loads – like those experienced by typical roads. This critical relationship of structural strength and high yield strain (elastic modulus), sets SoilTech MK. III polymer stabilization technology apart from conventional geotechnical design methodologies based on empirical cement stabilization of road layers. Resilient modulus is determined using the triaxial test. The test applies a repeated axial cyclic stress of fixed magnitude, load duration and cycle duration to a cylindrical test specimen. While the specimen is subjected to this dynamic cyclic stress, it is also subjected to a static confining stress provided by a triaxial pressure chamber. It is essentially a cyclic version of a triaxial compression test; the cyclic load application is thought to more accurately simulate actual traffic loading. In December 2015 Polyroads in conjunction with geotechnical expert, Alan Parrock from ARQ Consulting Engineers completed a set of Triaxial tests on SoilTech Mk. III polymer stabilizers. These tests were conducted by SANAS certified, GEOSTRADA laboratories. SoilTech MKIII is a water based polymer used for the stabilisation of road construction base and subbase layers. As such, ARQ submitted the required quantities of a G5 type material, classified according to COLTO standards, and SoilTech soil stabilisation product to Geostrada, a SANAS accredited soils laboratory, for testing. Foundation Indicator, moisture-density and California Bearing Ratio (CBR) tests were conducted on the soil to determine grading, compactibility and strength characteristics. Saturated Consolidated Undrained (SCU) triaxial tests were then conducted on the soil alone, as well as a mixture of the soil and stabiliser. This would allow for evaluation of change in shear strength and stress-strain behaviour of the soil due to addition of soil stabiliser.

From Figure 4, a considerable increase in friction angle can be seen at corresponding strains for the soil and stabiliser mixture. CBR reading after 30 days on the G5 material stabilized with SoilTech Mk. III polymer was 142 at 100% MOD AASHTO.

SoilTech Mk. III , a third generation polymer binder and is the flagship product of the company. It is a road stabilization agent specifically designed for mine haul-road stabilization, where excessive loading occurs and where all-weather roads are required. This technology is now used in commercial road design. SoilTech Mk. III has been extensively utilized in base and sub-base stabilization using in-situ materials, throughout the developing world, SoilTech stabilizing polymers are elastomers, which gain strength from mechanical compaction and do not become brittle when cured. The elastomer is able to flex under load and unlike cement stabilization, will not crack under excessive loading – one aspect in reducing layer work in design phases

SoilTech MK III stabilizers have been purposely designed to penetrate through the road’s base layer, into the sub-base layer, via capillary action. This sub-base strengthening process is of significant importance as we are not only stabilizing the road’s base layer, but also creating a semi-bound sub-base. From a road design perspective, a strengthened sub-base may negate the need for further layer-works. SoilTech, in many instances, transforms insitu materials that would normally be classified as unusable or waste materials, into suitably modified aggregates, for use in base and sub-base layer construction.

Consider a 300mm pavement layer which has under- gone 1.5mm settlement, correlating to a 0.5% strain. At this strain the friction angle of the stabilised material is 28û, compared to the soil alone, which possesses a friction angle of 17û. Sample failure for the soil only sample occurred at strains of some 0.5%, while failure of the soil and stabiliser mixture occurred at strains of some 2%. Furthermore, the plot of deviator stress versus axial strain (provided below) indicates that at 0.2% strain and confining pressure of 400kPa, the soil/stabiliser mixture exhibits a stiffness of some 85MPa (gradient of the stress-strain line), which is considerably higher than the soil alone, for which a stiffness of 56MPa was calculated.

Aside to this, the failure stress for the soil stabiliser are more or less double those for the soil alone. Results of the tests conducted on the soil and soil/stabiliser mixture indicate that addition of the stabiliser results in considerable improvement of the strength and stress-strain behaviour of the material. The soil/stabiliser mixture withstood 4 times (some 2% versus 0.5%) more strain before failure than the soil alone – after 30 days curing. Resilient modulus is determined using the triaxial test. The test applies a repeated axial cyclic stress of fixed magnitude, load duration and cycle duration to a cylindrical test specimen. While the specimen is subjected to this dynamic cyclic stress, it is also subjected to a static confining stress provided by a triaxial pressure chamber. It is essentially a cyclic version of a triaxial compression test; the cyclic load application is thought to more accurately simulate actual traffic loading.

SoilTech, in many instances, transforms insitu materials that would normally be classified as unusable or waste materials, into suitably modified aggregates, for use in base and sub-base layer construction. Structural strengths achieved with SoilTech polymer stabilization, exceed international single axle loading (80kN) standards by several hundred percent. A further major design benefit of SoilTech polymer, is the fact that although very impressive load bearing strengths are achieved, the elastomeric properties of SoilTech also provides unsurpassed tensile performance, for road stabilizing products. Engineers are now able to reduce the number of supporting layers, traditionally used to support conventional rigid or flexible pavement designs. SoilTech is normally mixed into the base layer, assuming that the sub-grade offers reasonable support. In some instances, the sub-base may also be stabilized with a lower dosage of SoilTech in order to provide further strength to in-situ materials. Reduced Aggregate SoilTech polymers are elastomeric by nature and therefore do not become brittle and cannot crack. In most instances one can use existing insitu soils and reduce the amount of layered work normally associated with cement stabilized roads.

These polymer advantages, addresses the pivotal factors influencing road construction costs. SoilTech stabilized roads, should be at least 30% more cost effective than conventional road designs.

1Concrete

Characteristics SoilTech Mk. III Polymer Stabilizer Conventional Concrete Stabilization

BASE LAYER

Stabilization Characteristics

SoilTech polymer gains strength from mechanical compaction, initially by a heavy roller and thereafter compaction by vehicle loads.

1Concrete stabilization is a chemical reaction curing process which needs time to cure, typically 4 weeks to reach 90% of strength

Time Delays The road is opened to traffic 24 hours after stabilization and sealed with a wearing course after five days

Stabilized roads normally remain closed for 28 days and then sealed with wearing course

Tensile Strength and Loading Characteristics

High Tensile Strength Elastomeric (flexible) properties of SoilTech will ensure that the base layer does not crack under excess loading. Supporting layers are not normally required

Low Tensile Strength Concrete stabilization although strong is non-flexible and rigid and will crack and breakup under excess loading. For this reason strong supporting layers are required

Sub-Base Strengthening

Although only the base layer is stabilized, SoilTech has been purposely designed with different sized polymer particles, allowing the smaller nano-particles to migrate into the in-situ sub-base layer via capillary action. The sub-base layer strength will be improved by a minimum of 50% with 90 days of stabilization. Regular DCP reports will confirm continuing strength improvements for up to 12 months.

To strengthen the sub-base a lower quantity of cement, typically 2%, will be mixed into the sub-base. This is assuming that the sub-base material is suitable for cement stabilization. Alternatively, borrow-pit material will have to be imported. Concrete stabilized roads will marginally, continue to improve in strength for up to 12 months

Maturing & Longevity

SoilTech being elastomeric by nature does not crack or become brittle, as it matures. SoilTech’s high tensile strengths will ensure that the stabilized layers substantially outlast comparatively designed concrete stabilized roads.

Concrete has a very low coefficient of thermal expansion and shrinks as it matures. All concrete structures crack to some extent, due to shrinkage and tension. Concrete that is subjected to long-duration forces is prone to creep.

COMPACTION INCREASES POLYMER BINDING CAPACITY SoilTech polymers gain binding strength from compaction. The greater the compaction, the better the polymer binds. Stabilized roads are opened to traffic 24 hours after construction. The kneading effect of vehicle traffic, further assists in accelerating the evaporation process of the surfactants and coalescing solutions surrounding the polymer chains. SoilTech polymers will start binding when exposed to air and the surfactant, aided by an alcohol mix, starts to evaporate. Once mixed into the road’s base layer /sub-base, mechanical compaction ensures that the chains of SoilTech polymers are firmly inter-locked with the soil particles. Materials that work best with SoilTech requires a plasticity range of between five and 15. The finer the materials, the more polymer will be required to coat the material particles.

Plasticity Index Scale and SoilTech Application Ratios

Various cross-linking polymers and activators may be added to poor materials in order to achieve the desired performance results. However, one needs to distinguish the economic feasibility between adding various polymers or activators to poor materials or whether it is more practical to merely import a better aggregate before stabilizing.

POLYMER MIGRATION SoilTech MK. III polymer stabilizer has been purposely designed, to allow for the migration of nano-polymers from the base layer into the sub-base layer through capillary action.

This Smart Material phenomena can be very advantageous when designing pavements, as it will act as a further performance enhancement and change the way of conventional road designing.

It is a road stabilization agent specifically designed for mine haul-road stabilization, where excessive loading occurs and where all-weather roads are required. This technology is now used in commercial road design. SoilTech Mk. III has been extensively utilized in base and sub-base stabilization using in-situ materials, throughout the developing world, SoilTech stabilizing polymers are elastomers, which gain strength from mechanical compaction and do not become brittle when cured. The elastomer is able to flex under load and unlike cement stabilization, will not crack under excessive loading – one aspect in reducing layer work in design phases

SoilTech MK III stabilizers have been purposely designed to penetrate through the road’s base layer, into the sub-base layer, via capillary action. This sub-base strengthening process is of significant importance as we are not only stabilizing the road’s base layer, but also creating a semi-bound sub-base. From a road design perspective, a strengthened sub-base may negate the need for further layer-works. SoilTech, in many instances, transforms insitu materials that would normally be classified as unusable or waste materials, into suitably modified aggregates, for use in base and sub-base layer construction. With SoilTech Smart Road Materials (SRM), one can;

• Reduce the consumption of quarry aggregate in conventional construction • in-situ materials can be used • Speed up construction time • Reduce construction costs • Dramatically reduce CO2 emissions • Reduced maintenance – as long as the asphalt wearing course layer is maintained, the

structural integrity of the road will be preserved, with the road pavement remaining rut-free and eliminating the need for base or sub-base maintenance.

Smart Road Materials are technological advancements in polymer technology that drives our innovation in new construction methodologies.

FACTORS INFLUENCING SOILTECH POLYMER STABILIZATION

Smart Materials are not miracle products and normal engineering diligence needs to be applied. Major factors influencing stabilization results are:

Item Factor Comments

i. Material or Aggregate It stands to reason that the better quality of aggregate used, the better results will be. Having said that, SoilTech has been designed to work with marginal materials.

Ideal Materials;

i. Plasticity index of 10 (will work with P.I of between (0 – 16)ii. Decent grading modulus (will also work with mixed grading of

<2mm)

Problem Some Materials;

i. material with very poor grading modulus– single sizedparticles that are non-plastic

ii. Percentage of SoilTech polymer applied

Normally SoilTech would be applied at 0.5% per MOD of the material

i. Where materials are poor, a higher dosage of SoilTechstabilizer is recommended. Perhaps 0.75% - 1.5% per MDD

ii. Modify SoilTech with higher dosage of cross-linking polymers

iii. Compaction Compaction is critical. SoilTech polymer binders do not form chemical crystallization bonds such as concrete when curing. SoilTech needs mechanical compaction.

One needs above average heavy compaction at OMC level, using a 12 tonne vibrating roller or heavier.

COMPACTION INCREASES POLYMER BINDING CAPACITY SoilTech polymers gain binding strength from compaction. The greater the compaction, the better the polymer binds. Stabilized roads are opened to traffic 24 hours after construction. The kneading effect of vehicle traffic, further assists in accelerating the evaporation process of the surfactants and coalescing solutions surrounding the polymer chains. SoilTech polymers will start binding when exposed to air and the surfactant, aided by an alcohol mix, starts to evaporate. Once mixed into the road’s base layer /sub-base, mechanical compaction ensures that the chains of SoilTech polymers are firmly inter-locked with the soil particles. Materials that work best with SoilTech requires a plasticity range of between five and 15. The finer the materials, the more polymer will be required to coat the material particles.

Plasticity Index Scale and SoilTech Application Ratios

Various cross-linking polymers and activators may be added to poor materials in order to achieve the desired performance results. However, one needs to distinguish the economic feasibility between adding various polymers or activators to poor materials or whether it is more practical to merely import a better aggregate before stabilizing.

POLYMER MIGRATION SoilTech MK. III polymer stabilizer has been purposely designed, to allow for the migration of nano-polymers from the base layer into the sub-base layer through capillary action.

This Smart Material phenomena can be very advantageous when designing pavements, as it will act as a further performance enhancement and change the way of conventional road designing.

SMART MATERIALS - FIRST COMMERCIAL TRIAL

1998, Radiokop, Johannesburg, South Africa, a road was constructed using polymers. At that stage the road was used by Maritz Quarries for a period of six years, carrying 120 trucks in and out of the quarry per day. Subsequently, 17 years later the quarry has closed and the road is now purely residential.

Construction Material available for constructing the road was classified as G7. The road was stabilized to a depth of 150mm with 0,5% polymer added to the MOD of the soil. The road was sealed with a cost effective 9mm chip & spray seal.

17 Years Later - 2015 The road has stood up remarkably well, considering that virtually zero maintenance has been performed on the road in 17 years. The 9mm chip and spray seal, is showing signs of serious fatigue and brittleness and weathering due to loss of bitumen from UV and traffic.

Lately, the Johannesburg Road Authorities (JRA) have been repairing the potholes.

The 150mm polymer stabilized base layer, still shows no signs of rutting or deformation. CBR readings have not changed over 16 years and are still in the region of 100%.

Polyroads invest heavily into research and development and have substantially increased the structural performance of their polymers since this Radiokop road was built 17 years ago.

Polyroads have constructed various mine haul roads throughout South Africa, with some carrying 300 ton haul truck loads on their unsealed roads.

Road Design & Certification

Polyroads, with the assistance of Professor Alex Visser from the University of Pretoria, have recompiled the Indian IRC37 road designs. Furthermore the company has very close working relationships with the Indian Institute of Technology (I.I.T), the Central Road Research Institute (C.R.R.I) as well as the National Highway Authorities of India (N.H.A.I)

Location: State of Haryana and Punjab

21 October 2010, SOMA ISOLUX NH ONE TOLLWAY (Pty) Ltd, the concessionary of the Six lane toll road Panipat-Jhalandhar Section of NH-1 from Km 69.000 to Km 387.100, met with the Hiway Projects of Ministry, National Highways Authorities of India and the State Governments.

In view of the advancement of technologies in the highway sector and the adoption of new proven technologies, permission was granted to the Concessionaire, namely SOMA Enterprise Ltd, to build a 5 Km section of the highway using SoilTech Mk. III polymer for stabilizing of the base layer. The project was completed 17 December 2010.

Design or Road

Due to the poor material available in Haryana, the flexible pavement was designed as a four layer structure, with only the base–layer being stabilized. Stresses and strains at critical locations were computed using the linear elastic model. To give proper consideration to performance aspects, the following three types of pavement distress , resulting from repeated (cyclic) application of track loads were considered;

i. Vertical compressive strain at the top of the sub-grade which can cause sub-grade deformation resulting in permanent deformation at the pavement surface.

ii. Horizontal tensile strain or stress at the bottom of the

bituminous layer which can cause fracture of the bituminous layer.

SoilTech Mk. III Stabilizer

SoilTech Mk. III , a third generation polymer binder and is the flagship product of the company. It is a road stabilization agent specifically designed for mine haul-road stabilization, where excessive loading occurs and where all-weather roads are required. This technology is now used in commercial road design. SoilTech Mk. III has been extensively utilized in base and sub-base stabilization using in-situ materials, throughout the developing world, SoilTech stabilizing polymers are elastomers, which gain strength from mechanical compaction and do not become brittle when cured. The elastomer is able to flex under load and unlike cement stabilization, will not crack under excessive loading – one aspect in reducing layer work in design phases

SoilTech MK III stabilizers have been purposely designed to penetrate through the road’s base layer, into the sub-base layer, via capillary action. This sub-base strengthening process is of significant importance as we are not only stabilizing the road’s base layer, but also creating a semi-bound sub-base. From a road design perspective, a strengthened sub-base may negate the need for further layer-works. SoilTech, in many instances, transforms insitu materials that would normally be classified as unusable or waste materials, into suitably modified aggregates, for use in base and sub-base layer construction. With SoilTech Smart Road Materials (SRM), one can;

• Reduce the consumption of quarry aggregate in conventional construction • in-situ materials can be used • Speed up construction time • Reduce construction costs • Dramatically reduce CO2 emissions • Reduced maintenance – as long as the asphalt wearing course layer is maintained, the

structural integrity of the road will be preserved, with the road pavement remaining rut-free and eliminating the need for base or sub-base maintenance.

BOTSWANA Customer: De Beers Diamonds Primary Contractor: Teraform Project: Stabilize Heavy Haul Roads

Location: Orapa, Botswana BACKGROUND In October 2012, Polyroads stabilized the ramp roads at Orapa Diamond Mine, the biggest open pit diamond mine in the world. The purpose was to reduce dust and water consumption.

The ramp roads were firstly stabilized to a depth of 160mm and then treated with Dust-Tech polymer, which was diluted with water at a ration of 1:50 and then sprayed on the ramp once per week.

Attached structural strength documentation shows Tholo Ramp road prior to stabilization with SoilTech Mk. III polymers and then after stabilization 37 000 m2 was stabilized

STABILIZATION – SOILTECH MK. III POLYMER The existing haul road was ripped to a depth of 150mm. SoilTech Mk. III polymer stabilizer,

supplied by Polymer Pavements was applied at a ratio 1.5 liters per m2. SoilTech Mk. III was diluted with water and sprayed over the ripped area. Further water was added to the soil and once the material was brought to optimium moisture levels, the road was profiled and compacted with a heavy 12 tonne roller and compacted to 98% MOD AASHTO. The road was opened to traffic 24 hours later. After three days of curing, a diluted concentrate of ClearTech polymer was sprayed over the road surface, using a water bowser. ClearTech assists in binding the top 10mm of road surface.

ASPHALTECH Cold Polymer Asphalt AsphalTech has been purposely designed to bind any non-plastic material into a useful wearing course seal. Worldwide, virtually all asphalt binders are now being modified with polymers, to increase performance. AsphalTech is a modified polymer, in direct competition to conventional asphalts. It is mixed and applied as a cold mix, using standard paving equipment. Furthermore, AsphalTech can be applied manually or by hand, where job creation and employment reduction is important. AsphalTech, will not bleed in the summer heat. The elastomer properties on AsphalTech, ensures that the material mix does not become brittle and does not crack. Polymer modification when compared to conventional asphalt, causes significant changes in the stress-strain behavior, the creep response and the non-newtonian flow patterns. The ability of AsphalTech polymers to elastically recover (creep response measured by monitoring the flow of a material under a load, and its elastic recovery when the load is removed) gives added durability to the AsphalTech seal and thereby reduces potholing. AsphalTech binder properties can reduce rutting, raveling, thermal cracking and stripping in the mix, as well as increase the stability and fatigue life.

Benefits

• Cost effective • Utilize any non-plastic aggregate • No gas burners or fire required • Seal gravel roads • Reduced potholing • Can be used to repair potholes in conventional blacktop seals • AsphalTech can be used to seal or repair existing tar roads • Ideal for job creation and manual application

Worldwide, virtually all asphalt binders are now being modified with polymers, to increase performance. AsphalTech is a modified polymer, in direct competition to conventional asphalts. It is mixed and applied as a cold mix, using standard paving equipment. Furthermore, AsphalTech can be applied manually or by hand, where job creation and employment reduction is important. AsphalTech, will not bleed in the summer heat. The elastomer properties on AsphalTech, ensures that the material mix does not become brittle and does not crack. Polymer modification when compared to conventional asphalt, causes significant changes in the stress-strain behavior, the creep response and the non-newtonian flow patterns. The ability of AsphalTech polymers to elastically recover (creep response measured by monitoring the flow of a material under a load, and its elastic recovery when the load is removed) gives added durability to the AsphalTech seal and thereby reduces potholing. AsphalTech binder properties can reduce rutting, raveling, thermal cracking and stripping in the mix, as well as increase the stability and fatigue life.

Benefits

• Cost effective • Utilize any non-plastic aggregate • No gas burners or fire required • Seal gravel roads • Reduced potholing • Can be used to repair potholes in conventional blacktop seals • AsphalTech can be used to seal or repair existing tar roads • Ideal for job creation and manual application

PolySeal

Dam & Barrier liners

In simplistic terms, PolySeal is a polymer modification of cement, which increases the tensile and flexural strength of mortars and concrete and reduces their brittle nature. Since the polymer-modified cement is a composite of two entirely different types of materials, the characteristics of the key components, that is cement and polymer, will be briefly described:

PolySeal is a composite consisting of PolySeal elastomeric cross-linking polymers, which is mixed as an admixture with cement and non-plastic aggregates.

Cement needs no introduction. Portland cement based concrete and mortar are among the most widely used construction materials in the world. Advantages include, relatively low cost, high stiffness, high compressive strength, non-flammability and ease of fabrication. However there are some serious limitations, such as low tensile strength and brittleness, which could affect the long-term durability. Polymer modification of cement paste increases its tensile and flexural strength and eliminates its brittle nature. PolySeal Geoliner is high-tech, cost effective and easy to apply. PolySeal is a water-soluble polymer spray-on barrier liner. The application of three coats of PolySeal emulsion will result in a highly elastic, non-toxic and flexible sealant for concrete or earthen dams or capping of waste stockpiles.

Benefits

Ø UV Resistant Ø Wind and weather proof Ø Does not become brittle and does not crack Ø Fire-proof (grass fires) Ø PolySeal conforms to any shape or size Ø Seamless Ø Easily repairable

BARRIER SYSTEMS / LINERS OVERVIEW Barrier systems are designed to prevent regional groundwater contamination by isolating leaching processes from the wider environment. Liners reduce the permeability at the base of the leach heap and consists of materials selected for low hydraulic conductivity and leakage control, such as compacted earth, bentonite clay, high-density polyethylene (HDPE), polyvinylchloride (PVC), or a combination of these.

State-of-the-art liners systems consists of several layers of liner material and incorporate leak detection systems and recovery devices. Capping or covering of solid mining waste is an effective and proven treatment technology. It can be used as a short- term interim measure or as a longterm or final action. Installation of a cap or cover on solid mining waste can reduce or eliminate erosion, fugitive dust emissions, and infiltration of water to prevent the migration of contaminants. Caps or covers eliminate direct exposure to solid mining waste by creating a physical barrier that prevents direct contact with the contaminants. SOUTH AFRICA “An analyses of international regulatory standards reported in the Geosynthetics Research Institute Report number 23 of 2007 showed the Minimum Requirements [in South Africa] to be one of the lowest regulatory containment standards word wide at that time, despite the South African water scarce conditions and hence limitations to assimilative capacity of the countries water resources.” Polyroads, is a member of various international environmental and water associations and understands the need to protect our environment. On 23 August 2013 the Dept. of Environmental Affairs promulgated the National Environmental Management: Waste Act,

2008 (Act No. 59 of 2008), the National Norms and Standards for Disposal of Waste to Landfill.

The Act covers various Class Landfill recommendations which is subject to the type of waste being disposed. Furthermore it states , in Chapter 2, Section 2 (a) design reports and drawings that must be certified by a registered, professional civil engineer prior to submission to the competent authority. Polyroads have the required personnel to assist applicants in the design of the containment barriers, using PolySeal in conjunction with the minimum engineering designs specified by the Act.

POLYSEAL – SPRAY-ON BARRIER GEO-LINER

In simplistic terms, PolySeal is a polymer composite, consisting of PolySeal elastomers and either cement, for barrier in treating alkaline waste materials or a composite of PolySeal and calcium carbonate fillers for barriers in treating acidic waste materials.

PolySeal Barrier Liners – are high-tech spray-on barrier liners, developed over many years by a team of international scientist collaborating with Polyroads. The first batch of PolySeal (Proudly South African) was manufactured in South Africa in 2010 and was an immediate success. Competing against dated barrier products such as bitumen and HDPE liners, PolySeal proved to be an instant success.

In 2013, Polyroads submitted an application to patent attorneys, namely DM Kisch INC , Patent 2013/03543. After much deliberation, in 2014, Polyroads decided to cancel the patent as it was simply revealing too much technical and development secrets. It was decided to revoke the patent.

POLYSEAL – SPRAY-ON BARRIER GEO-LINER

In simplistic terms, PolySeal is a polymer composite, consisting of PolySeal elastomers and either cement, for barrier in treating alkaline waste materials or a composite of PolySeal and calcium carbonate fillers for barriers in treating acidic waste materials.

PolySeal Barrier Liners – are high-tech spray-on barrier liners, developed over many years by a team of international scientist collaborating with Polyroads. The first batch of PolySeal (Proudly South African) was manufactured in South Africa in 2010 and was an immediate success. Competing against dated barrier products such as bitumen and HDPE liners, PolySeal proved to be an instant success.

In 2013, Polyroads submitted an application to patent attorneys, namely DM Kisch INC , Patent 2013/03543. After much deliberation, in 2014, Polyroads decided to cancel the patent as it was simply revealing too much technical and development secrets. It was decided to revoke the patent.

ASPHALTECH Cold Polymer Asphalt AsphalTech has been purposely designed to bind any non-plastic material into a useful wearing course seal. Worldwide, virtually all asphalt binders are now being modified with polymers, to increase performance. AsphalTech is a modified polymer, in direct competition to conventional asphalts. It is mixed and applied as a cold mix, using standard paving equipment. Furthermore, AsphalTech can be applied manually or by hand, where job creation and employment reduction is important. AsphalTech, will not bleed in the summer heat. The elastomer properties on AsphalTech, ensures that the material mix does not become brittle and does not crack. Polymer modification when compared to conventional asphalt, causes significant changes in the stress-strain behavior, the creep response and the non-newtonian flow patterns. The ability of AsphalTech polymers to elastically recover (creep response measured by monitoring the flow of a material under a load, and its elastic recovery when the load is removed) gives added durability to the AsphalTech seal and thereby reduces potholing. AsphalTech binder properties can reduce rutting, raveling, thermal cracking and stripping in the mix, as well as increase the stability and fatigue life.

Benefits

• Cost effective • Utilize any non-plastic aggregate • No gas burners or fire required • Seal gravel roads • Reduced potholing • Can be used to repair potholes in conventional blacktop seals • AsphalTech can be used to seal or repair existing tar roads • Ideal for job creation and manual application

SOUTH AFRICA Customer: Petra Diamonds Mine, Koffifontein Project: Lining of settlement dam Location: 100Km from Kimberley, Northern Cape In June 2013 Petra Diamonds appointed Polyroads to construct a barrier liner at their Koffiefontein diamond mine approximately 100 Kms from Kimberley. Adjacent to the dam are prestine wetlands and it was critical to prevent leaching from the mine’s dam. The dam area is approximately 8 000 m2. October 2013, saw prolonged major sit-in strikes occurring at Koffiefontein mine, preventing contractors from entering the premises. In order to save time and disruption by Union strikers, Polyroads decided to prepare the PolySeal geoliners off-site. The geoliner rolls were sprayed and treated off-site in rolls of 150m long by 5.2m wide. The rolls were then transported to site, entering the mine via an alternate entrance. The PolySeal geoliner rolls were anchored in place with anchor trenches. The geoliner roles were overlapped, pinned. The project was completed in 10 days. Thereafter the dam was filled with water.

Location: Flagstaff, Eastern Cape Polyroads were appointed in September 2013 to line the Mzintlava fresh water dam with a synthetic PolySeal geoliner over 40,000 m2. The company used their unique patented PolySeal geoliner, to line the floor and walls of the clay-clad dam. The PolySeal liner consists of an underlying geofabric, which is pinned to the base layer. PolySeal is then sprayed over the geofabric in three consecutive layers, with a high-pressure guniting machine. The elastomeric PolySeal emulsion, is applied as a liquid and when cured, will form a strong synthetic geoliner, which is totally UV, acid and alkaline resistant. The primary benefits of PolySeal, is the fact that there are no seems or joints, that can leak, as the entire construction is totally homogeneous. PolySeal remains flexible and expandable and does not become hard or brittle in the sun. Construction was completed in 90 days.

SOUTH AFRICA – AGGREGATE LOSSES

Gravel is a non-renewable resource obtained from borrow pits or quarries. It is estimated that approximately 30 million m3 of gravel is lost on our roads per annum due to erosion and traffic. This volume equates to the size of Table Mountain – imagine a Table mountain disappearing every year. Much of this material ends up in our rivers and lakes.

There are over 600 000 km of unsealed roads in South Africa. It is estimated that each 240 tons of gravel disappear per km on our gravel roads

(Sabita – information Series)

SOUTH AFRICA – AGGREGATE LOSSES

Gravel is a non-renewable resource obtained from borrow pits or quarries. It is estimated that approximately 30 million m3 of gravel is lost on our roads per annum due to erosion and traffic. This volume equates to the size of Table Mountain – imagine a Table mountain disappearing every year. Much of this material ends up in our rivers and lakes.

There are over 600 000 km of unsealed roads in South Africa. It is estimated that each 240 tons of gravel disappear per km on our gravel roads

ASPHALTECH Cold Polymer Asphalt AsphalTech has been purposely designed to bind any non-plastic material into a useful wearing course seal. Worldwide, virtually all asphalt binders are now being modified with polymers, to increase performance. AsphalTech is a modified polymer, in direct competition to conventional asphalts. It is mixed and applied as a cold mix, using standard paving equipment. Furthermore, AsphalTech can be applied manually or by hand, where job creation and employment reduction is important. AsphalTech, will not bleed in the summer heat. The elastomer properties on AsphalTech, ensures that the material mix does not become brittle and does not crack. Polymer modification when compared to conventional asphalt, causes significant changes in the stress-strain behavior, the creep response and the non-newtonian flow patterns. The ability of AsphalTech polymers to elastically recover (creep response measured by monitoring the flow of a material under a load, and its elastic recovery when the load is removed) gives added durability to the AsphalTech seal and thereby reduces potholing. AsphalTech binder properties can reduce rutting, raveling, thermal cracking and stripping in the mix, as well as increase the stability and fatigue life.

Benefits

• Cost effective • Utilize any non-plastic aggregate • No gas burners or fire required • Seal gravel roads • Reduced potholing • Can be used to repair potholes in conventional blacktop seals • AsphalTech can be used to seal or repair existing tar roads • Ideal for job creation and manual application

Smart Material Engineering

ASPHALTECH Cold Polymer Asphalt AsphalTech has been purposely designed to bind any non-plastic material into a useful wearing course seal. Worldwide, virtually all asphalt binders are now being modified with polymers, to increase performance. AsphalTech is a modified polymer, in direct competition to conventional asphalts. It is mixed and applied as a cold mix, using standard paving equipment. Furthermore, AsphalTech can be applied manually or by hand, where job creation and employment reduction is important. AsphalTech, will not bleed in the summer heat. The elastomer properties on AsphalTech, ensures that the material mix does not become brittle and does not crack. Polymer modification when compared to conventional asphalt, causes significant changes in the stress-strain behavior, the creep response and the non-newtonian flow patterns. The ability of AsphalTech polymers to elastically recover (creep response measured by monitoring the flow of a material under a load, and its elastic recovery when the load is removed) gives added durability to the AsphalTech seal and thereby reduces potholing. AsphalTech binder properties can reduce rutting, raveling, thermal cracking and stripping in the mix, as well as increase the stability and fatigue life.

Benefits

• Cost effective • Utilize any non-plastic aggregate • No gas burners or fire required • Seal gravel roads • Reduced potholing • Can be used to repair potholes in conventional blacktop seals • AsphalTech can be used to seal or repair existing tar roads • Ideal for job creation and manual application
