Maruti CRMB
Crumb Rubber Modified Bitumen

Maruti CRMB is a special type of value added Bitumen where the properties have been improved by blending with crumb rubber and special type of additives. Maruti CRMB with enhanced physical properties, is more resistant to temperature variations, weathering and high traffic loads. This leads to improved pavement life, reduced maintenance costs and excellent driving comfort.
