Towards Future Green Roads

APPROACH TO ENVIRONMENTAL

MITIGATION


2/39

Environmental Mitigation

We have taken this earth on lease from

our future generations. It is our duty to

return it to them in liveable condition if

not better. Striving for sustainability

throughprudent use of limiting naturalresources and restraint in emissions is

the call of the day.

This realization is at the core of all innovations at Zydex


3/39

The following contribute to sustainability in road construction Reducing the usage of limiting resources like bitumen, aggregate etc.

Extending the life cycle of the roads, so as to defer the demand for such

resources

Reducing fuel consumption leading to reduction in emission

VisionTo create a Sustainable Futurefor the world by achieving Resource Extension

economically, by reducing usage of limiting resources and extending life cycle

Zydex Nanotechnology : A Game Changer

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.

10-30% savings

in Road Construction Cost

Allows optimization of road section designs leading to lower

thicknesses of expensive top layers
