Greening our Roads Approach To create a Sustainable Future for the world, by achieving Resource Extension economically, by reducing usage of limiting resources and extending life cycle
Ensuring Green Roads through Reducing the usage of limiting resources like bitumen, aggregate etc. Use of local soil Extending the life cycle of the roads, so as to defer the demand for limiting resources Reducing fuel consumption leading to reduction in emission
Ensures New Organosilane Nanotechnology Dimensional stability (zero or low free swell index) Dimensionally stable soil bases can be achieved at the cost of Rs.400-800/ m 3 Strength stability - CBR between 50-100 100% stress transfer due to chemically bonded waterproofed bond coats Elimination of moisture susceptibility due to chemically bonded bitumen mixes
Results Improved stiffness retention with dimensional and strength stability Permeability reduction of 10-7 to 10-8 cm/sec Breathability of the soil base structure to allow vapors to escape but reduce the water ingress Reduced aggregate & bitumen layer thickness, enabling the design objective for green roads
Zydex Nanotechnology : A Game Changer Reduction in top layers thickness with 10-30% savings SOIL LAYERS Zydex Nanotechnology makes the soil impermeable to water, reduces expansiveness and stabilizes almost any type of soil to improve its bearing strength manifold. If used with 1% cement, it can improve the California Bearing Ratio (CBR) to even 100 or above. This is a game changer, as stronger soil base would now allow optimization of road section design. BOND COATS Prime & Tack coats become 100 % waterproofed, due to penetration and chemical bonding. This also ensures 100% coverage at lower residual bitumen, reducing fatigue failure. ASPHALTIC LAYERS Chemical bonding between aggregates and asphalt eliminates moisture induced damage to asphaltic layers. Improves strength and flexibility with higher compaction density.
