The specific Improvements of nkl Polymer and Rubber modified Bitumen produced by this new process are as under :

Jai Polymer and Rubber Modified Bitumen improves resistance to cracking, resulting in stronger and more durable overlays for corridors in the areas of extreme climatic conditions and heavy traffic loads.
It reduces deformation on road, this is specifically true at elevated temperature (50^oC to 70^oC), where rutting is excessive. It is achieved due to improved viscosity and elastic recovery of polymer and rubber based modified bitumen, compared to conventional bitumen.
Promote binder adhesion and cohesion to mineral aggregates
The stripping level and raveling of aggregates from surface are reduced and offer resistance to creep deformation.
Low temperature brittleness properties of bitumen in pavement due to excessive aging are improved as evident from improved ductility and elastic recovery values at low temperature.
Polymer & Rubber based modified binder extend life of pavement by 50% to 100%, when compared to conventional bitumen overlays or renewal as proved by field trials.
Polymer & Rubber based modified binders act as multigrade bitumen and are economical, when life cycle cost is taken into consideration. It can be used as membrane overlays for preventive maintenance of pavement.

Easy to Use : Jai Polymer and Rubber Modified Bitumen can be used in the construction, maintenance and renewal of roads, airfields and heliports in a manner similar to the existing hot mix process using the same manpower, tools and plant.
