What is bitumen CRM?
CRMB: Crumb Rubber Modified Bitumen
CRM is a mixture of bitumen and modified bitumen rubber is intrusive. The viscosity modifier rubber used asphalt binder and temperature resistance as well as resistance against brittle at low temperatures increases. CRMB has good adhesion to mineral mass, and thereby reduce brittleness and deformity.
The advantages of CRMB:
The price is right
Increased resistance to breakage increases the efficiency of asphalt on weather conditions and heavy traffic.
Reducing road deformation at high temperatures
More and return to the bitumen viscosity elastic than normal
Better adhesion properties
Stability and flexibility
Construction and repair of roads with high traffic
Construction of the runway
