crmb 50

Definition of CRMB 50

CRMB 50, also known as Crumb Rubber Modified Bitumen, is a specialized asphalt binder infused with approximately 50% recycled rubber crumb obtained from discarded tires. This unique blend enhances the elasticity, rut resistance, and fatigue life of asphalt pavements, making them more durable and resilient to heavy traffic loads and environmental stresses.

Advantages of Crumb Rubber Modified Bitumen

Enhanced Durability: The addition of rubber crumb improves the elasticity and resilience of asphalt pavements, reducing cracking and rutting.

Extended Service Life: Pavements require less frequent maintenance and repairs, resulting in long-term cost savings.

Environmental Sustainability: By repurposing scrap tires into road infrastructure, It contributes to waste reduction and promotes circular economy principles.

Applications of the CRMB 50

Use in various road construction applications, including:

Highways and Expressways

Urban Roads and Streets

Airport Runways

Parking Lots and Industrial Areas
