Abstract

The Gaza Strip is one of the most populated area in the world, and the least in terms of

the vast green areas that allow water permeability through it. The Gaza Strip also faces

an urban renaissance where the increase in the number of buildings and concrete roofs,

the paving of the main roads and many vital projects in the city, which increases the

runoff of rainwater and reduces the access and infiltration to the aquifer. Due to the

difficulty of providing water and the lack of other sources of water such as rivers,

researchers were required to find ways and alternatives to provide water, and benefit

from the runoff of rain water, as the rainy season is short in Gaza Strip, and this is one

of the objectives of this study. This study aims at the possibility of producing concrete

block pavement (Interlock), which allows water infiltration and use in places with low

loads such as public spaces, car parking, playgrounds, etc. In this study, a number of

practical experiments were conducted to identify the infiltration rate of water through

concrete block pavements by simulating the fall of rainwater on a 1 m2 concrete block

pavement to determine the permeability of the water drier and to reach the highest

possible permeability without runoff surface water. The study was divided into two

parts. The first part was production porous interlock. This was done in the automatically

factory for construction industries in order to ensure quality and efficiency. Three types

of gravel were used (Folia, Adsia and Semesmia) in varying proportions and the surface

layer of stone (Basalt) has been dispensed. Four basic mixtures were selected and with a

change in water and cement ratios, sixteen samples were produced. After processing the

samples, we performed the required tests (density, compressive strength, and

absorption). The second part of the study was designed to calculate the amount of water

running through the 16 samples. This was done by simulating the intensity of the

rainfall (60 mm / h) for each of them, for 60 consecutive minutes. After the results were

collected, good results were obtained compared to the results of the other researches .

The results show that the permeability rate ranges from 37% to 50%. This ratio is

controlled by a number of determinants, including the different percentages of the

gravel mixture. The mixtures formed from high percentages of the folia and adsia

aggregate gave a high percentage of permeability but at the expense of compressive

strength, The sample has an inverse relationship between the compressive strength of

the interlocking stone and permeability. It also controls the ratio of permeability of

water and cement ratios.

1.1 Background

The population of the Gaza Strip reaches more than “according to the Palestinian

Central Bureau of Statistics” 1.8 inhabitants and this number will reach more than 2.6

Million inhabitants by year 2025. The groundwater is considered to be the main water

source that supply the residents of the Gaza Strip for different purposes (domestic

agricultural or industrial.) Gaza coastal aquifer is limited where its thickness is in

between120-150 Meter in some areas of the western part of the coastal strip and too few

meters in the east and southern part of the coastal aquifer (Coastal Municipalities Water

Utility, CMWU Report, 2010). However, the Gaza strip lacks the procedures that help

in recharging the groundwater storage where there are high amounts of runoff due to the

impervious surfaces of asphalts, interlock which can have negative impacts including

sediment transport, erosion, and pollutant transport. On the other hand, the shortage of

water in the aquifer should be taken in consideration, then the water must be collected

and re-injected to underground or reused for agricultural sector. Therefore, using porous

or permeable pavement are recommended to give appropriate solutions are alternatives

to these issues.(Jendia ,Almadhoun,2014). Permeable pavement allows storm water to quickly infiltrate the surface layer to enter a

high-void aggregate base layer. The captured runoff is stored in this reservoir until it

either percolates into the underlying sub-grade, or is routed through a perforated under

drain system to a conventional storm water conveyance. Appropriately designed

interlocking permeable pavement may reduce the amount of pollutants reaching

receiving waters (James and Langsdorff, 2003). All of this forces to search for an urgent

solution that can avoid the previous harmful effects, and this research tries to help in

solving this problem by studying the possibility of using porous interlock in the Gaza

strip.

The technique of this type of interlock is designed to allow water to pass through the

surface into an underlying layer and eventually into the underlying soil so the quantity

of storm water runoff is significantly reduced, and the infiltrate is also filtered by the

porous pavement structure in the process. These permeable pavements are appropriate

for low intensity use, such as overflow parking areas, parking lots, residential roads, and

pedestrian walkways, so they have gained high popularity over the last two decades as

alternatives to conventional road construction materials due to their ability to reduce

3

urban runoff (McNally, DeProspo Philo, &Boving, 2005).

A permeable interlock pavements can be used in the building, roads, parking lots,

residential streets, sidewalks, and pedestrian places.

1.2 Permeable pavement systems (PPS)

PPS are a very effective management practice for a wide range of pollution control in

storm water. They facilitate infiltration for large areas with a structurally safe pavement

for use by pedestrians, or shopping areas, park areas and driveways as well as areas with

moderate traffic use. A common principal of permeable pavement in the case of storm

water management is the collection, treatment and infiltration of storm water to support

groundwater restoration. PPS are a good solution, particularly in sustainable drainage

systems, for recycling of storm water and control of contamination from harmful

substances, such as hydrocarbons and heavy metals. The aggregate size of the sub-base

and base should be precise so that the permeable pavement can quickly drain runoff and

store the water to avoid flash floods.

Studies conducted overseas have proved that a properly designed pervious pavement

system will function in an urban environment effectively to manage stormwater

hydraulically and to improve water quality (Zhang, 2006).

1.3 Permeable Pavement

Permeable pavements, an alternative to traditional impervious pavement, allow storm

water to drain through them and into a stone reservoir where it is infiltrated into the

underlying native soil or temporarily detained. They can be used for low traffic roads,

parking lots, driveways, pedestrian plazas and walkways. Permeable pavement is ideal

for sites with limited space for other surface storm water. The following permeable

pavement types are illustrated in Figure (1.1):

permeable interlocking concrete pavers (i.e., block pavers);

plastic or concrete grid systems (i.e., grid pavers);

pervious concrete; and

porous asphalt.

Depending on the native soils and physical constraints, the system may be designed

with no under drain for full infiltration, with an under drain for partial infiltration, or

with an impermeable liner and under drain for a no infiltration or detention and

filtration only practice Figure (1.2). Permeable paving allows for filtration, storage, or

infiltration of runoff, and can reduce or eliminate surface storm water flows compared

to traditional impervious paving surfaces like concrete and asphalt.

1.4 Statement of the problem

The available water resources in the Gaza Strip are limited and do not fulfill the

increasing water demand. The Strip depends mainly on the groundwater from the

coastal aquifer, which has a safe yield of only 98 Mm3 per year (Hamdan 1999), while

the overall water demand was estimated at 180 Mm3 per year in 2018 (PWA, 2018 ).

This leads to an annual water deficit in the water resources of about 70 Mm3, which has

its impact on the supplied water quantities as well as their water quality due to sea water

intrusion and deep groundwater up coning. The average annual rainfall gives a bulk

amount of water of about 114 Mm3 (PWA 2007), from which only 45 Mm3 infiltrate

naturally to the aquifer which forms only 40% of the total rainfall (Hamdan and

Muheisen 2003).

With increased population and climate change water shortage problems are troubling

mankind all over the world. How to harvest the water during rainfall events for use at

times of need is of major interest subject to engineers, environmentalists and to the

community. with urbanization, more impervious road and roof surfaces appear resulting

in increased runoff from rainfall. Also don’t forget that Gaza Strip suffering during

winter seasons from flooding, and photo (1.3) show the situation during heavy rain.

This fact led to search about the useful solution of this problem and to improve of the

quality and the quantity of groundwater and Preserving water sources, and to be more

focus to find the tools for treatment of storm water and recharge it to the groundwater

(Khalaf, 2005). Figure (1.3) shows the bad storm water situation in Gaza strip.

This chapter of thesis considers the theoretical part of study, presents and collects the

information of permeable pavements, the different types of permeable pavements,

Benefits of permeable pavement, Use of permeable pavement, Construction,

maintenance and performance of permeable pavement. The preparation of the layer

under permeable pavement includes material selection for the bedding and base course

The major characteristic of permeable pavements were reviewed and investigated the

traditional concrete block types, some studies were conducted in this concern and the

outcome of these studies was reviewed.

2.2 Overview of Permeable Pavement

Permeable pavements are alternatives to traditional impervious asphalt and concrete

pavements. Interconnected void spaces in the pavement allow for water to infiltrate into

a subsurface storage zone during rainfall events. In areas underlain with highly

permeable soils, the captured water infiltrates into the sub-soil. In areas containing soils

of lower permeability, water can leave the pavement through an under drain system.

2.2.1 Types of Permeable Pavements

There are five types of permeable pavements: permeable asphalt (PA), permeable

concrete (PC), permeable interlocking concrete pavers (PICP), concrete grid pavers

(CGP), and plastic grid pavers (PG). The pictures in Figure (2.1) illustrate the five types

and a variation of fill for plastic grid pavers.

Figure (2.1): Type of permeable pavements (NRMCA, 2004)

12

Permeable concrete (PC)

Is a mixture of Portland cement, fly ash, washed gravel, and water. The water to

cementitious material ratio is typically 0.35 – 0.45. Unlike traditional installations of

concrete, permeable concrete usually contains a void content of 15 to 25 percent,

which allows water to infiltrate directly through the pavement surface to the

subsurface. A fine, washed gravel, less than 13 mm in size (No. 8 or 89 stone), is

added to the concrete mixture to increase the void space. An admixture improves the

bonding and strength of the pavements. These pavements are typically laid with a 10

to 20 cm (4 – 8 in) thickness and may contain a gravel base course for additional

storage or infiltration. Compressive strength can range from 2.8 to 28 MPa (400 to

4,000 psi) (National Ready Mixed Concrete Association, NRMCA, 2004).

Permeable asphalt(PA)

Consists of fine and course aggregate stone bound by a bituminous-based binder.

The amount of fine aggregate is reduced to allow for a larger void space of typically

15 to 20 percent. Thickness of the asphalt depends on the traffic load, but usually

ranges from 7.5 to 18 cm (3 – 7 in). A required underlying base course increases

storage and adds strength (Ferguson, 2005).

Permeable interlocking concrete (PICP)

Pavements are available in many different shapes and sizes. When lain, the blocks

form patterns that create openings through which rainfall can infiltrate. These

openings, generally 8 to 20 percent of the surface area, are typically filled with pea

gravel aggregate, but can also contain top soil and grass. ASTM C936 specifications

(200 1b) state that the pavers be at least 60 mm (2.36 in) thick with a compressive

strength of 55 MPa (8,000 psi) or greater. Typical installations consist of the pavers

and gravel fill, a 38 to 76 mm (1.5 – 3.0 in) fine gravel bedding layer, and a gravel

base-course storage layer (ICPI, 2004).

Concrete grid pavers (CGP)

CGP are typically 90 mm (3.5 in) thick with a maximum 60 × 60 cm (24 × 24 in)

dimension. The percentage of open area ranges from 20 to 50 percent and can

contain topsoil and grass, sand, or aggregate in the void space. The minimum

average compressive strength of CGP can be no less than 35 MPa (5,000 psi). A

typical installation consists of grid pavers with fill media, 25 to 38 mm (1 – 1.5 in)

of bedding sand, gravel base course, and a compacted soil subgrade (ICPI, 2004).

13

Plastic reinforcement grid pavers (PG)

Also called geocells, consist of flexible plastic interlocking units that allow for

infiltration through large gaps filled with gravel or topsoil planted with turf grass. A

sand bedding layer and gravel base-course are often added to increase infiltration

and storage. The empty grids are typically 90 to 98 percent open space, so void

space depends on the fill media (Ferguson, 2005). To date, no uniform standards

exist; however, one product specification defines the typical load-bearing capacity

of empty grids at approximately 13.8 MPa (2,000 psi). This value increases up to 38

MPa (5,500 psi) when filled with various materials.

2.3 Permeable Interlocking Concrete Pavement (PICP)

Permeable interlocking concrete pavement, also referred to as PICP, consists solid

concrete paving units with joints that create openings in the pavement surface when

assembled into a pattern. The joints are filled with permeable aggregates that allow

water to freely enter the surface. The permeable surface allows flow rates as high as

(2,540 cm/hr). The paving units are placed on a bedding layer of permeable aggregates

which rests over a base and subbase of open-graded aggregates. The concrete pavers,

bedding and base layers are typically restrained by a concrete curb in vehicular

applications. The base and subbase store water and allow it to infiltrate into the soil

subgrade. Perforated underdrains in the base or subbase are used to remove water that

does not infiltrate within a given design period, typically 48 to 72 hours. Geo synthetics

such as geotextiles, geogrids or geomembranes are applied to the subgrade depending

on structural and hydrologic design objectives. Separation geotextiles are used on the

sides of the base/subbase to prevent entrance of fines from adjacent soils(Borst, 2010).

2.3.1 History of (PICP)

Road paving with tightly fitted stones resting on a flexible granular base dates back to

the Roman Empire. Even though, stones are still being used as paving material the

modern version of this road technique utilizes concrete blocks instead. [Rada et. al.

1990]. The use of concrete block pavement CBP for roads began in the Netherlands

after the Second World War. Brick paving was the traditional surface material in the

Netherlands before the Second World War. Because of the coal shortages brick had

been unavailable as a result CBP had been used as a substitute. The substitution became

hugely successful. After the war, the roads of Rotterdam were almost entirely

constructed from concrete block paving [Pritchard and Dawson 1999]. This technology

quickly spread to Germany and Western Europe as a practical and attractive method

useful for both pedestrian and vehicular pavement [Rada et. al. 1990]. Over the past 40

years CBP has gained rapid popularity as an alternative to conventional concrete and

asphalt pavements. The CBP is now a standard paving surface in Europe where over

100,000,000 m2 are placed annually [Ghafoori and Mathis 1998].

In Australia

Interlocking concrete blocks were introduced into Australia in 1976. By 1979 sales

figures had reached 2 km2 per annum and are currently increasing rapidly. Until

recently, very little scientific investigation had been carried out into the performance of

15

block paving under traffic and the design and construction of block pavements had been

based on European experience or modifications of flexible pavement design procedures.

The first full-scale testing of block pavements of any significance in Australia began in

1977 at the University of New South Wales test track.

2.3.2 Typical permeable interlocking concrete pavement cross section.

Figure (2.2) illustrates PICP components. The figure shows a partial infiltration design

with drainage to accommodate some water that does on enter low infiltration soils.

PICP over high infiltration subgrade soils may not require an underdrain(s) and these

are called are called full infiltration designs. Other designs over expansive or fill soils or

close to buildings may enclose the pavement structure with geomembrane (impermeable

liner). An outlet pipe provides temporary storage and outflow control. This design

approach also can be used for water harvesting or for horizontal ground source heat

pumps. The use of a geomembrane to restrict infiltration into the soil subgrade is often

called a no infiltration design.

Figure (2.2): PICP components (PICP Institute)

2.3.3 Requirements of (PICP)

16

PICP may help achieve compliance with many national, provincial, state and local

regulations as well as transportation agency design requirements for stormwater runoff

control. These requirements may include the following:

Limits on impervious cover (i.e., roofs and pavements) and resulting runoff .

Runoff volume storage and/or infiltration to reduce overflows, especially

combined sewer overflows.

Meeting total maximum daily load (TMDL) requirements for receiving waters.

Managing water quality volume capture and or quantity storm events.

2.4 Concrete block pavement (CBP)

Pavements have been surfaced with stone blocks since ancient times and even up to the

end of the 19th century surfaces of dressed stone or hardwood blocks were common.

Developments in concrete technology and improved plant for block manufacture led to

acceptance of small concrete blocks for pavement surfaces in Western Europe about 60

years ago(CCA, 1988).

2.4.1 Features of Concrete Block Pavements Concrete paving blocks are utilized in a variety of commercial, municipal and industrial

applications. The primary reasons for selecting CBP over other paving surfaces are low

maintenance, ease of placement and removal, reusage of original blocks, aesthetics

appeal, and immediate usage after installation or repair [Ghafoori and Mathis 1998].

CBPs are able to withstand heavy loads and resists aggressive environments as good as

a rigid concrete pavement. Besides that, with its wide range of colors, textures and

patterns, CBPs provide excellent aesthetic appearance opportunities.

Aesthetic Appeal

Concrete block paving is available in a constantly expanding variety of colors, shapes

and textures and can be installed in numerous bonds and laying patterns [Interpave

2003]. Concrete pavers offer unique aesthetic benefits when compared to other forms of

pavement in their ability to integrate and harmonize with both the built and natural

environment [Concrete Masonry Association of Australia 1997]. In Figure (2.3) some

applications of paving blocks are provided.

17

Figure (2.3): Paving Block Applications [Interpave, 2003]

CBPs offer numerous opportunities in residential and pedestrian areas by their, light

reflection, water absorption, noise generation features and are often used for traffic

management (Figure 2.4) [Concrete Masonry Association of Australia 1997, (Interpave,

2003).

Figure (2.4): Paving Block Applications for Traffic Management [Interpave, 2003].

18

2.4.2 Applications of concrete block pavement

Concrete pavers are a versatile paving material, which due to the availability of many

shapes, sizes and colors, have endless streetscape design possibilities. The use of

concrete block paving can be divided into the following categories:

Roads:

Main roads, residential roads, urban renewal, intersections, toll plazas, pedestrian

crossings, taxi ranks, steep slopes, pavements (sidewalks), and figure (2.5) show

example of road application.

2.4.3 Pattern in Concrete Block Pavements

Concrete block pavements are produced in a variety of shapes, typical paving block

shapes available in the Gaza strip are shown in Figure (2.10).

Concrete block pavers come in a variety of shapes and sizes.

If we consider for a moment the aesthetics of concrete block paving, three fundamental

aspects present themselves:

Shapes

Colors

Illustrated below Figure (2.11) are some of the range of standard colors available. Many

pigments are used by paving block manufacturers which, together with aggregates from

22

different areas and various cements, produce a huge variety of colors from which to

choose. Multiblends are produced by the incomplete mixing of pigments and give a

pleasing effect when laid over large areas.

Patterns

Laying patterns of pavers are identified as being either herringbone, basket weave,

or stretcher as shown below. Each of these may be laid at either 90o or 45o to the

line of edge restraints. A variation of stretcher is the Zig zag running bond (CMA,

2004). Figure (2.12),shows the pavement pattern.

2.4.5 Installation of concrete block pavements

This pavement structure is commonly used for both pedestrian and vehicular

applications. Pedestrian areas, driveways, and areas subject to limited vehicular use

are paved with (60 mm) thick. Streets and industrial pavements should be paved

with units at least (80 mm) thick.

2.5 Porous pavements (P.P)

Porous pavements are those made with built-in void spaces that let water and air pass

through. They are the most radical, most rapidly developing, and most controversial

way of restoring large parts of the urban environment. They have been called “the holy

grail of environmental site design” and “potentially the most important development in

urban watersheds since the invention of the automobile (Schaus, 2007).

In the late 1960’s, research into a new type of pavement structure was commencing at

The Franklin Institute Research Laboratories (FIRL) in the United States. With the

support of the United States Environmental Protection Agency (EPA), a porous

pavement program was developed. This new pavement structure was initially installed

in parking lots (Schaus, 2007).

Porous pavements have been installed since the early 1980’s throughout the United

States, installed over on parking lots, pathways, and trails for universities, libraries,

religious centers, prisons, industrial parks, commercial plazas, and municipal

buildings(Adams, 2006).

The original proposed structure of a porous pavement consisted of an open graded

surface course placed over a filter course and an open graded base course (or reservoir)

all constructed on a permeable subgrade. Stormwater infiltrations using pervious

pavements have been investigated by researchers as a method of managing storm water

(Schaus, 2007).

25

2.5.1 Porous concrete’s environmental performance

Properly installed porous concrete has void space of 11 to 22 percent (the amount varies

with aggregate type). Its surface infiltration rate is over 55 inches per hour, and can

exceed 100 inches per hour.

Like other porous paving materials, porous concrete reduces stormwater rate and

volume. Stormwater can be discharged through a perforated pipe at the bottom of the

pavement, or at the top of the base reservoir, or water can be allowed to overflow at the

pavement surface. Each type of drainage outlet produces different proportions of

detention, treatment, infiltration, evaporation, and lateral overflow. Rainwater

infiltration through a porous pavement into the underlying soil reduces stormwater

volume and restores natural subsurface flow paths. Where slowly permeable soil

prohibits significant soil infiltration, and water is discharged through a perforated pipe

in the pavement, a porous pavement can perform detention comparable to that in off-

pavement reservoirs and ponds: the peak discharge of stormwater from the bottom of a

porous pavement is later and lower than that of the rainfall entering it at the top; the

total volume of discharge is lower. Reduction of stormwater flow reduces downstream

flood frequency, stream channel erosion, sediment loads, and combined-sewer

overflows.

It is believed that common urban pollutants are treated in porous concrete, as they are in

other types of porous pavement. Metals like cadmium and lead released by automobile

corrosion and wear are captured in porous pavements’ voids along with the minute

sediment particles to which the ions are characteristically attached. Capturing then

metals prevents them from washing downstream and accumulating inadvertently in the

environment. In the void spaces, oil leaked from automobiles is digested by naturally

occurring micro biota that inhabit the abundant internal surface area. The oil’s

constituents go off as carbon dioxide and water, and very little else; the oil ceases to

exist as a pollutant.

Porous pavements combine stormwater management with pavement function in a single

structure. Developments planned to benefit from this combination tend to cost less than

those having impervious pavements with separate stormwater management facilities

that incur costs of land acquisition, excavation, piping, and outlet structures.

Porous pavements can give urban trees the rooting space they need to grow to full size,

providing the shade, cooling and air quality for which the trees are planted. The rooting

zone is an aggregate base, made of large, single-sized aggregate that bears the

26

pavement’s load. Into the aggregate’s void space is mixed 15 to 20 percent by volume

of nutrient- and water-holding soil; the remaining unfilled void space maintains aeration

and drainage. The base mixture makes the base into a “structural soil”, while the porous

surface admits vital air and water to the rooting zone. This is a revolutionary new way

to integrate healthy ecology and thriving cities: living tree canopy above, the city’s

traffic on the ground, and living tree roots below.

2.5.2 Porous concrete’s potential

Porous pavements are important because they can solve urban environmental problems

at the source. In new suburban growth, they protect pristine watersheds. In old town

centers, redevelopment and reconstruction are opportunities for environmental

rehabilitation simultaneously with urban renewal.

The hydrologic and structural success of porous concrete depends on correct selection,

design, installation, and maintenance. Failures — clogging and structural degradation

— result from neglecting one or more of these steps. Porous pavements’ potential

application is vast. To date, porous pavements constitute only a minute fraction of the

paving done each year in the United States. But their rate of growth, on a percentage

basis, is very high, primarily because of public concern about and legal requirements for

stormwater management. Properly applied porous pavements can also enlarge urban

tree rooting space, reduce the urban heat-island effect, reduce traffic noise, increase

driving safety, and improve appearance. Therefore their selection and implementation

are integral parts of the multi-faceted concerns of urban design, and all of their effects

are considered together in evaluations of potential benefits and costs.

2.6 Drainage design for permeable pavement

Drainage design is only one important part of the integrated pervious pavement system.

According to different drainage designs underneath the pervious surface, pervious

pavements can achieve objectives when used as a stormwater management method.

Normally the designed flows will be estimated by the Rational Method, as show in eq.

(2.1).

Q = C I A---------------------------------------- (2.1)

Where,

Q = Storm water quantity, (m3/h)

C = Coefficient of Runoff, (dimensionless)

I = Rainfall intensity, (mm/h)

A = Catchment Area, (m2)

27

According to the local environmental and stormwater resource requirements, different

drainage pipe designs can be integrated into the pervious pavement systems at design.

For example, if the local groundwater table is at a significant low depth, stormwater is

an ideal resource to recharge groundwater. Under this situation, the aim of the pervious

pavement is to allow more water to percolate into the groundwater bringing it up ready

for reuse. In this situation the drainage pipe is laid close to the bottom of bedding layer.

2.7 Storm water data in Gaza

The necessary information required by the research have been collected from the

relevant institutions such as Palestinian water authority (PWA), municipalities, the

Ministry of Local Government (MOLG), the Ministry of Agriculture (MOA), Coastal

municipal water utility (CMWU) and local NGOs.

The available stormwater quantities that flow from the existing urban areas in Gaza

were calculated to be 22 Mm3 every year. Since urbanization in the Gaza Strip is a

continuous process, the flowing stormwater quantities from the planned land use were

estimated to be 37 Mm3 every year (Hamdan, and Nassar, 2007).

The available groundwater system which is part of the coastal aquifer showed fast

response to natural rainfall infiltration. However, in the dry season, the decrease in the

water table was around 1.5 meters due to groundwater abstraction. This means that the

supply to the aquifer is much less than the demand through abstraction. At the same

times, there it gives us an indication that, artificial recharge of groundwater with

stormwater will have quick positive effect to balance the gap between aquifer supply

and demand (Hamdan, and Nassar, A., 2007).

2.7.1 Rain Intensity

Improvement of the reliability of Rain Intensity (RI) measurements as obtained by

traditional tipping-bucket rain gauges and other types of gauges (optical, weighting,

floating/siphoning, etc.) is therefore required for use in climatologic and hydrological

studies and operationally e.g. in flood frequency analysis for engineering design.

Standardization of high quality rainfall measurements is also required to provide a basis

for the exchange and valuation of rainfall data sets among different countries, especially

in case transboundary problems such as severe weather/flood forecasting, river

management and water quality control are operationally involved. Figure(2.18) shows

the intensity duration frequency curve in Gaza city, where the intensity readings taken

28

2.8.1 Advantages of concrete block pavements

Two of the major advantages of concrete block pavements are their aesthetic appeal and

their high strength. In addition the riding surface of good quality concrete offers high

durability, skid resistance, abrasion and scuffing resistance.

Block pavements may be opened to traffic immediately on completion of construction,

the surface is not as smooth as asphalt or cast in situ concrete so interlocking pavements

are generally recommended for where traffic speeds are less than 50-60 km/h. Because

of its segmental nature, interlocking blocks can be recycled. Once the pavement has

been broken, paving blocks can be lifted and recovered for re-use and only a small stock

of replacement blocks needs to be maintained. This facilitates access to underground

services and permits the subsequent restoration of the pavement with little material cost

and no discontinuity of the surface. Pavement shape correction if required can also be

accomplished at low material cost (CCA, 1988).

2.8.2 Permeable paving risk

Common concerns about permeable paving include the following:

Risk of Groundwater Contamination:

Most pollutants in urban runoff are well retained by infiltration practices and soils and

therefore, have a low to moderate potential for groundwater contamination (Pitt et al.,

1999). Chloride and sodium from de-icing salts applied to roads and parking areas

29

during winter are not well attenuated in soil and can easily travel to shallow

groundwater. Infiltration of deicing salt constituents is also known to increase the

mobility of certain heavy metals in soil .

Risk of Soil Contamination:

Available evidence from monitoring studies indicates that small distributed stormwater

infiltration practices do not contaminate underlying soils, even after more than 10 years

of operation (TRCA, 2008).

Winter Operation:

For cold climates, well-designed mixes can meet strength, permeability, and freeze-

thaw resistance requirements. In addition, experience suggests that snow melts faster on

a porous surface because of rapid drainage below the snow surface. Also, a well-

draining surface will reduce the occurrence of black ice or frozen puddles (Cahill

Associates, 1993, Roseen, 2007). Permeable pavement is typically designed to drain

within 48 hours. If freezing should occur before the pavement structure has drained,

then the large void spaces in the open graded aggregate base creates a capillary barrier

to freeze-thaw. Permeable pavers have the added benefit of having enough flexibility to

handle minor heaving without being damaged. Permeable pavement can be plowed,

although raising the blade height 25 mm

may be helpful to avoid catching pavers or scraping the rough surface of the porous

pavement. Sand should not be applied for winter traction on permeable pavement as this

can quickly clog the system(TRCA, 2008).

On Private Property:

If permeable pavement systems are installed on private lots, property owners or

managers will need to be educated on their routine maintenance needs, understand the

long-term maintenance plan, and may be subject to a legally binding maintenance

agreement. An incentive program such as a storm sewer user fee based on the area of

impervious cover on a property that is directly connected to a storm sewer . could be

used to encourage property owners or managers to maintain existing practices.

30

Clogging:

Susceptibility to clogging is the main concern for permeable paving systems. The

bedding layer and joint filler should consist of 2.5 mm clear stone or gravel rather than

sand. Key strategies to prevent clogging are to ensure that adjacent pervious areas have

adequate vegetation cover and a winter maintenance plan that does not include sanding.

For concrete and asphalt designs, regular maintenance that includes vacuum-assisted

street sweeping is necessary. Isolated areas of clogging can be remedied by drilling

small holes in the pavement or by replacing the media between permeable pavers.

Road Salt:

Care needs to be taken when applying road salt to permeable pavement surfaces since

dissolved constituents from the road salt will migrate through the bedding and into the

groundwater system. A well-draining surface will reduce the occurrence of black ice or

frozen puddles and requires less salt than is applied to impervious pavement (Roseen,

2007).

Structural Stability:

Adherence to design guidelines for pavement design and base coarses will ensure

structural stability. In most cases, the depth of aggregate material required for the

stormwater storage reservoir will exceed the depth necessary for structural stability.

Reinforcing grids can be installed in the bedding for applications that will be subject to

very heavy loads.

Heavy Vehicle Traffic:

Permeable pavement is not typically used in locations subject to heavy loads. Some

permeable pavers are designed for heavy loads and have been used in commercial port

loading and storage areas.

2.9 Maintenance of (PICP):

Openings in the surface of permeable pavements are susceptible to clogging by

sediment from passing vehicles, wear of the pavement surface, and runoff from nearby

disturbed soils. It is therefore essential to ensure that nearby soils are adequately

secured prior to, during, and after installation of permeable pavement.

Pretreatment systems may be required to help prevent clogging. Legally binding

easements or covenants may be needed to ensure proper maintenance techniques are

followed.

31

Maintenance should be performed on a regular basis. To prevent clogging, the

permeable pavement surface should be vacuum swept followed by high-pressure jet

hosing at least four times per year. Do not apply sand or ash to permeable pavement

for snow removal purposes. Signage should be posted at locations where permeable

pavement is installed to advise maintenance crews of this requirement.

Routine Maintenance

The following provides a checklist for PICP routine maintenance:

Inspect, and if necessary, clean the surface using regenerative air equipment to

remove debris and sediment in the spring and late fall.

Repair/replant vegetative cover for areas up slope from the PICP

Replenish aggregate in joints if more than ½ in. (13 mm) from paver chamfer

bottoms

Repair all paver surface deformations exceeding ½ in. (13 mm)

Repair pavers offset by more than ¼ in. (6 mm) above/below adjacent units or

curbs, inlets etc.

Replace cracked paver units impairing surface structural integrity

Clean and flush underdrain system if slow draining

Clean drainage outfall features to ensure free flow of water and outflow

Remedial Maintenance

Repair and/or reinstatement of damaged edge restraints and resulting movement

in the pavers; this may require removal and reinstatement of adjacent paving

units

Repair localized settlement greater than ½ in. (13 mm) and rutted pavement

areas

Repair outflow features, piping, energy dissipaters, erosion protection systems,

etc. as required

Winter Maintenance

Avoid the use of winter sand for traction; if used, remove with regenerative air cleaning

equipment in the spring (regenerative equipment does not evacuate jointing materials)

Remove snow with standard plow/snow blowing equipment

Stockpile plowed snow onto turf or other vegetated areas and not on the PICP.

32

Monitor temperatures and apply anti-icing/deicing materials such as sodium

chloride, calcium chloride or magnesium calcium acetate.

2.10 Conclusion of previous studies

After reviewing the previous studies and during researching to complete the thesis, we

were review a lot of studies related to porous/permeable/pervious pavements with

respect to interlocking concrete pavers, all of these pavements are designed to allow

free draining through the structure. The local studies is more less than international

studies ,and these studies as follow:

In Gaza

Eng. Mahmoud Madhoun with supervision of Prof. Shafiq Jendia present study " the

Effect of Joints, Block Shape and Pavement Pattern on the Permeability of Concrete

Block Pavement (Interlock Pavement).The conclusion of the study was:

The results show that the using rectangular block tile 10x20 cm gives the

highest percentage of water permeability.

The increase of joints between interlock tiles, no large effect has been noticed in

the percentage of water permeability during low intensity of water, while little

increase was observed in the water permeability during the high water intensity

but the increase in the continuity of water permeability grows with the increase

of joints in cases of obstructive dust and dirt on the surface of the pavement.

In world

Study by (H.M. Imran, Shatirah Akib and Mohamed Rehan Karim), University of

Malaya, Kuala Lumpur, Malaysia (3 March 2013), on " Permeable pavement and

stormwater management systems" The conclusion of the study was:

Permeable pavement system PPS play a vital role in reducing contaminants from

infiltrating stormwater runoff and provide great facilities for storage and the

reuse of stormwater as well

as in preserving the hydrologic function of a site.

PPS can be applied to reduce the increased pressure on groundwater extraction.

permeable pavement technology, is a green approach to collecting, storing,

treating and reusing stormwater from residential, industrial commercial areas.

Study by (Mulian Zheng,Shuanfa Chen, and Binggang Wang) Mar 2012 on " mix

design method for permeable base of porous concrete " describe that:

33

Porous concrete should have certain porosity to fully drain water and in addition

to particular structural strength.

Percentage of porosity range from 30-35 % .

The test was designed with consideration of three factors cement dosage ,water

cement ratio ,and aggregate gradation .

3.1 Introduction

An update of what was presented in the first and second chapters and a confirmation of

the objectives that have been indicated that the use of permeable pavements to manage

storm water. It is clear that to achieve an efficient and durable solution, a careful design

of pavement layers and choice of surface pavement product. The objective of the

present study is to understand the infiltration through interlock pavement surface only.

In order to reach the goals of the letter we making a number of concrete mixtures and

manufacturing of permeable Interlock using different aggregate type, cement and water

and then do all the necessary tests in the laboratory. The second part, it was decided to build a practical experiment pavement to monitor the

infiltration rates through the pavement structure. The simulated rainfall events were

modeled using the small pipe and nozzles on steel box. The water infiltrated through the

pavement collected by funnel.

Processing of the mixes and collecting of material were at the automatically factory in

Gaza.

Firstly, this chapter presents the laboratory studies carried out to determine the

parameters necessary to build the pavement and to monitor the infiltration rate.

Secondly, to describe how experimental work has been done and the possible scenarios

to achieve study objectives.

3.2 Processing of samples and laboratory testing

This study depends on laboratory testing as the main procedure to achieve study goals,

and the test were conducted using equipment and devices available in the laboratories of

Association of Engineers-Gaza to evaluate the properties of aggregate material and

sand. The sieve analysis is carried out for each aggregate type to obtain the grading of

aggregate sizes.

Laboratory tests are divided into three stages:

1st Stage of Testing

This stage includes the collection of materials for the processing of permeable Interlock

samples, such as types of gravel, sand and cement, then the samples are processed in the

factory in order to control the quality, mixing characteristics and manufacturing

specifications.

36

2nd Stage of Testing

This stage were in the laboratory and includes the work of the necessary tests for the

materials used in the processing of Interlock samples and also conduct tests on the

samples Interlock.

3rd Stage of Testing

At this stage a design were developed to calculate the permeability of the samples that

have been processed, The design of experiment was constructed in a 1.0x1.0m with

0.25m depth from steel box. and Figure (3.1) Flow chart displays the laboratory testing

procedure as the three stages.

3.5.5 Mixture design method

The design approach of Porous Interlock is mainly based on proper selection of

narrowly graded coarse aggregate and varying the paste volume until the target

properties are achieved.

The water content that should be used in Porous Interlock depends mainly on the

gradation and physical characteristics of aggregate as well as the cementitious materials

type and content.

A successful mix design for Porous interlock should consist of a balanced composition

of materials to ensure the best performance in terms of permeability, strength, and

durability.

The required quantity was calculated in each mixture for the possibility of producing

about 170 stone Interlock by using the three types of aggregate Folia, Adsia and

Semsimia, in addition to sand, cement and water according to the ratio to Table (3.10), The quantities of water and cement are set by reference to w/c ratio .

Table (3.17) shows the quantity of materials for each mix.

4.1 Introduction

Results of experimental work were obtained and discussed to achieve the study

objectives, which include studying the properties of aggregates, cement, and water on

the permeability of water in porous interlock pavement.

The results are presented in this chapter in two stages. First, recording all results of 16

processed samples as compressive strength, absorption and density. Second stage shows

the permeability percentage of water with different interlock samples.

4.2 Result of experimental scenarios

In the previous chapter, after conducting all the tests for the materials needed for

processing the samples, we manufactured the samples. After processing the samples, we

divided the samples into two parts. The first part of the samples was immersed in water

for 24 hours to determine the percentage of absorption. The second part of the samples

was treated with water for 28 days. to know the compressive strength .

4.2.1 Result of Compressive Strength and Absorption for 16 samples

The result of average Compressive Strength and average Absorption is record in

Table (4.1). The average results of 10 stones result are show in appendix B

Palestine Standards Institution (PSI) shows the characteristics and specifications as:

The compressive strength of concrete block has been stated to range between 45

and 50 MPa.

The maximum absorption when placed in water for 10 minutes no more than 2%

and when placed in water for 24 hour no more than 5%.

4.3 Result of permeability scenarios

The simulation consist of (60mm/h) rainfall storms of uniform intensities to test the

infiltration rate. The flow rate of 60 mm/h was suitable to flow through the nozzles.

The nozzles of the rainfall simulator were placed directly above the experimental area.

The funnel underneath the pavement is also placed within the area to collect water.

In order to obtain the infiltration characteristics through the bedding layer and flow

through the whole pavement structure for rainfall event, the water flow through the

bottom of the pavement was collected at 1 minute interval.

4.4 Discussion

After the completion of the necessary tests in the laboratory on 16 samples, the

compressive strength, absorption and the permeability, and these results were presented

in the previous tables, we will discuss these result and compare with previous studies.

As shown in the table (4.4), the results of the compressive strength were range between

229-370 kg/cm2, and it was a good results compared to the Palestinian specifications in

the case of a common interlock, and the reason in these results are:

The percentage of voids between aggregate that range from 40-45%, which is

shown in compressive strength results in mixtures # 2,4.

Also water and cement ratios were controlled in the compressive strength

values, where we note that the lowest value of compressive strength in sample

2-3, and the highest value in sample 1-1.

For the results of permeability it range from (37-50%), that according to the previous

tables, and after discussion and analysis we note that:

The result of permeability were Converged.

The highest values of permeability were in mixture No. 4 where the percentage

of folia aggregate is the largest percentage among mixtures and therefore the

percentage of voids are high.

In the case of large water cement ratio, the permeability is low.

Since one of the objectives of the research is to calculate the amount of permeability, it

means that the best mixture is the mixture No. 4-1, where the highest permeability

49.92.

Conclusions and Recommendations

80

5.1 Conclusions

The following conclusions can be drawn:

a) The study has shown the possibility of producing and using porous interlock in

Gaza Strip and studying the infiltration rate of water through this Interlock and

reduce the amount of water accumulated on the surface as runoff water as much

as possible by using a variety of experiences.

b) It was found that it is possible to use new types of aggregate such as Folia and

Adasia, which are not used in the traditional Interlock industry and in varying

proportions.

c) Through the study, identified four basic samples with varying percentages of the

three types of Aggregate Folia, Adasia, and Somsmia, with a change in the

percentage of cement and water. This is a good indicator for researchers that it is

possible to use other percentages of the aggregate and produce other samples for

research and finding other results.

d) There is a possibility to produce and manufacture all the available forms of

Interlock in the local markets and be permeable for water, but in this study

restricted Interlock Square 10 × 20 cm, because of the difficulty of changing the

templates used during the tests because the cost of time and effort and money to

change.

e) The results show that there is an inverse relationship between compressive

strength and permeability, as the greater the compressive strength of the sample,

the less permeability.

f) The results showed that the permeability rate ranged between (37%-50%) and

the results were obtained and the joints between the interlock are closed with

mortar but if the joints through the testing are openings, was possible to obtain

the results of the multiplication of permeability.

g) In this research, a medium percentage of intensity rate was used, which is 60

mm/h, but it is possible to use other rates such as (15mm/h, 45mm/h, 120mm/h)

and finding other results, which opens the way for other researchers to complete

other research on the subject.

81

5.2 Recommendations

a) In order to approve and confirm the success and integrity of the results of the

laboratory, these results should be applied on the field and also for an integrated

understanding of the subject.

b) Through the results that have obtained, especially the compressive strength

results of the samples, study recommends to use of porous interlock in areas

with lights load tolerance such as playgrounds, parking, and corridors.

c) It is important to get benefit from amounts of water that is collected and not

neglected then, re-injected into groundwater aquifer to reduce the water

problem.

d) It is recommended to increase the efficiency of water leakage through porous

Interlock to be layers under the porous interlock layers more porosity by

replacing the layer of base coarse with a layer of gravel and the use of geotextile

and the use of pipes under these layers to collect water.

e) It is recommended to conduct similar studies about making mix concrete tile that

has special specification to permeable water through the tiles and consist of

compounds with water permeability properties.

f) It is recommended to use additives during sample casting to increase sample

compressive strength.

g) Government, institutions, municipalities and researchers should integrate efforts

toward preparing and implementing water management plan reinforcing the

environmental sustainability by taking and support important issues to

development the infrastructure.
