What Is Geogrit Road System ?

07:57

Geogrit Road System is a road building technique that uses only non-toxic and environmental friendly chemicals to make roads. By not using stones as the basic materials for road building, Geogrit Road System therefore provide a more inexpensive, fast construction time and good quality road to the consumers.

Soils are treated with chemicals (BP2G) to make it hard to withstand heavy vehicles to pass through and thus eliminates the need to use stones as the materials for the road base. As stones contributes the most in term of costing in road building, by eliminating them would resulted in a great deal of saving in the overall road building costs.

Having a good solid road base is not enough to ensure a long lasting and comfortable road. Geogrit Road System provides a layer of flexible road surface sealant (BP3G) to eliminate dust accumulation during dry season and formation of water puddles during wet season on road surface.
The combinations of having these good strong base and protected road surfaces make Geogrit Road System the best alternative in road construction technique.

The Products

08:01

There are two types of material used to construct Geogrit Road. The first is called BP2G. This is the chemical that is used to treat the road base. It is a blend of various chemicals that functioned to harden the soil by the process called soil stabilization.

The second product is called BP3G and it functioned to eliminate dust and water puddles on the road surfaces. It is a bitumen/asphalt-based material with the addition of other materials to enhance the performances.

The Installation Process

1. A motor grader is use to loose soil surface to the required depth of 150 mm. This can be achieved by using the ripping teeth of the motor grader.
2. Then a rotorvator (driven by a tractor) is use to scarify the loosen soil for a better mix.
3. Apply the BP2G solution on the already loosen soil. BP2G should be mixed with water at a required proportion in a water tank. The solution is then spray on the soil by gravity.
4. Again the rotorvator is use to mix BP2G and the soil to achieve even moisture content. The rotorvator should follow behind the water tank.
5. Repeat the process for 3 to 4 passes. This would bring the mixed material of BP2G and the soil to the optimum moisture content state.
6. Use the motor grader to form camber to provide proper drainage of water along side of the road. The gradient is approximately 1:20
7. The treated soil is then compacted with a 10 tons vibrating compactor.
8. Curing should be carried out the next day by spraying plain water (if required) and followed by a few passes of compaction.
9. Applying the BP3G using a spray pump to the treated road surface for better control on wear and dusts. Usually BP3G is applied 1 or 2 days after the road base has been treated depending on the weather conditions.
10. Sand or quarry dust or chipping or pre-mixed would then be laid on top of the BP3G layer immediately after spraying the sealant.

BENEFITS

08:21

1. AFFORDABLE PRICE
All weather, low maintenance soil roads can be achieved with Geogrit
for a small fraction of resurfacing costs.

2. REDUCES OVERALL ROAD LABOR AND MAINTENANCE PROBLEMS
Geogrit increases road stability and resilience and decreases water penetration of the

road base. These factors reduce the problems of washboard effects, rutting and potholes.

The result is longer road wear and less road and vehicle maintenance costs.

3. USES IN-SITU BASE MATERIAL, AVOIDING THE NEED TO IMPORT EXPENSIVE

AGGREGATE
Geogrit technology uses the existing soil materials thus avoiding the need to import

materials.

4. REQUIRES THE SAME TYPE OF MACHINERY AS CURRENT RESURFACING

OPERATION.
Geogrit is easily applied using standard construction equipment and requires about the

same effort as current resurfacing operations. The only step added to the normal

scarifying and grading procedure is the addition of Geogrit formulation with enough water

to wet soil particles and achieve optimum moisture for compaction.

5. INCREASES COMPRESSIVE STRENGTH
Geogrit acts as a catalyst to accelerate and strengthen road base material bonding. Geogrit

creates a more dense, cohesive and stable base which increases in compressive strength

over time.

6. IMPROVES ROAD BEARING CAPACITY
Geogrit improves the structural integrity of the road base and increases load bearing

capacity after curing. This extends the life of the road.

7. LOWERS WATER PERMEABILITY
Tighter soil configurations discourage the migration of water that normally occurs in the

voids between particles. Roads and soil beds constructed with Geogrit have greater

resistance to water penetration and deterioration.

8. SAFE HANDLING NON-TOXIC NON-FLAMMABLE
BP2G is non-toxic and non-flammable. No special handling or containment procedures are

required.

9. ENVIRONMENTALLY SAFE
Geogrit’s products are not harmful to human, animals, fish or vegetation and

are biodegradable.
