2) CONCEPT DESCRIPTION

3) THE PRODUCT – ENVIROTAC II

• Concentrated Liquid Water-based Co-polymer

• Designed to solidify non-organic soils resulting in increased strength & ductility compared

with conventional constructed road base layers.

• Eliminates the need for import of large volumes aggregates currently used for road base

3) THE PRODUCT – ENVIROTAC II

• made in U.S.A

3) THE PRODUCT – ENVIROTAC II

• Overseas transportation by ISO Liquid Containers or by Standard Containers with Totes

ISO Liquid Container – 24,000 litres capacity Totes – 1,000 litres capacity

3) THE PRODUCT – ENVIROTAC II

• Until 2009 primarily used for military purposes in desert environment

US Air Force take-off & landing sites in Iraq and Afghanistan

3) THE PRODUCT – ENVIROTAC II

IMPORTANT NOTE:

ENVIROTAC II is currently the only global available liquid soil-stabilizing product

able to solidify soils in extreme saline environment and does not require other

binding materials such as Portland Cement or lime/fly-ash.

Envirotac II can be diluted with water containing up to 4% salts or with ‘’grey’’

water from waste-water plants.

3) THE PRODUCT – ENVIROTAC II

• Diluted in fresh, salt or grey-water at an average mix-ratio 4 ltr H2O : 1 ltr Envirotac II

3) THE PRODUCT – ENVIROTAC II

• ENVIROTAC II eliminates the need for import of large volumes aggregates for road base

3) THE PRODUCT – ENVIROTAC II

• ENVIROTAC II mixed directly with in-situ soil (sand only!)and added carbon dye for coloring

• 4,500 m2 completed in less than 4 hours and ready for striping and traffic after 24 hours

• ASPHALT PAVING NOT NECESSARY

4) THE EQUIPMENT – TEREX Reclaimers

4) THE EQUIPMENT – TEREX Reclaimers

• Thorough compaction immediate after mixing ENVIROTAC II with in-situ pre-compacted soils

4) THE EQUIPMENT – TEREX Reclaimers

• Treated areas ready for traffic and/or asphalt paving after 12 to 24 hours curing

4) THE EQUIPMENT – TEREX Reclaimers

ALTERNATIVE APPLICATION METHOD – Asphalt Recycling:

Most recent developments and executed projects in U.S.A have also shown

that ‘’on-the-spot’’ recycling of asphalt (full depth asphalt recycling) using the

TEREX RS600C and TEREX RS950b while mixing Envirotac II and Carbon (for

coloring) directly with the on-site milled materials results in a new road

surface after compaction with equal appearance as new asphalt however

better in strength and performance.

One single TEREX Reclaimer can process up to 15,000m2 in one day

operation. The treated areas are ready for traffic after 12 to 24 hours curing!

4) THE EQUIPMENT – TEREX Reclaimers

• ALTERNATIVE APPLICATION METHOD - ‘’on-the-spot’’ Asphalt Recycling

Microprocessor controlled pump for calibrated injection of Envirotac II/H2O and Carbon (for coloring) into milled asphalt and soil.

Hose connected to Water Truck

Damaged Asphalt

Reclaimed Asphalt/Road Base Materials mixed with Envirotac II & Carbon (for coloring) will after compaction result in a new improved pavement layer. Conventional asphalt paving is therefore not necessary.

4) THE EQUIPMENT – TEREX Reclaimers

• Full Depth Asphalt recycling

4) THE EQUIPMENT – TEREX Reclaimers

• Immediate compaction after mixing ENVIROTAC II with ‘’on-the-spot’’ pulverized Asphalt

4) THE EQUIPMENT – TEREX Reclaimers

• crushing old asphalt for discard or complicated recycling methods NOT NECESSARY!

5) ROAD CONSTRUCTION DETAILS

• CONVENTIONAL METHOD

5) ROAD CONSTRUCTION DETAILS

• CONVENTIONAL METHOD – Imported aggregates (Macadam) applied at 0.15m per layer

5) ROAD CONSTRUCTION DETAILS

• NEW CONCEPT - ENVIROTAC II for construction of road base layer

5) ROAD CONSTRUCTION DETAILS

• NEW CONCEPT - Water diluted ENVIROTAC II mixed with in-situ soils

6) THE ENVIRONMENT & CARBON FOOTPRINT

• ENVIROTAC II is completely harmless for the environment and is used in eco-sensitive areas

6) THE ENVIRONMENT & CARBON FOOTPRINT
