Shiva CRMB is a crumb rubber based Bitumen modifier. A complete modifier manufactured by blending chemically treated crumb rubber with Asphalt / Bitumen & Bismides chemicals. Increasingly heavy traffic conditions are spelling disasters like cracking, potholing, raveling, deformation, creep failure & shortening of life of asphaltic pavements. Severe climatic conditions with daily and seasonal variations of atmospheric temperature on roads. Rains/ water Strip away asphaltic pavements. There is thus an increase in maintenance cost and vehicle operation cost.
