CRMB 50 | Crumb Rubber Modified Bitumen for Heavy Duty Pavements

Overview of CRMB 50

Crumb Rubber Modified Bitumen 50 (CRMB 50) is a high-performance modified asphalt binder developed by blending selected penetration grade bitumen with recycled crumb rubber derived from end-of-life tires, using controlled thermal and mechanical processes.

This advanced modification enhances the elastic behavior, deformation resistance, and fatigue performance of the binder, making CRMB 50 a reliable solution for heavy-duty pavements exposed to high traffic loads and elevated temperatures.

CRMB 50 is supplied as a finished binder from bitumen production units and is later used in asphalt plants to manufacture long-lasting, rubber-modified asphalt mixtures.

Performance Benefits of CRMB 50

Crumb Rubber Modified Bitumen 50 is engineered to outperform conventional penetration grade bitumen in demanding conditions:

  • High Elastic Recovery
    Improves pavement flexibility and resistance to thermal and load-induced cracking.

  • Superior Rutting Resistance
    Maintains structural integrity under heavy axle loads and high pavement temperatures.

  • Extended Fatigue Life
    Enhances resistance to repeated traffic stresses, reducing premature pavement failure.

  • Reduced Aging and Oxidation
    Slows binder hardening over time, improving long-term pavement performance.

  • Sustainable Engineering Solution
    Incorporates recycled rubber, supporting environmentally responsible infrastructure development.

Applications of CRMB 50

CRMB 50 is widely used in pavement structures where durability and performance are critical, including:

  • Highways and expressways

  • Roads with heavy truck and freight traffic

  • Urban arterial roads and intersections

  • Airport runways and taxiways

  • Industrial zones, logistics centers, and parking facilities

  • Pavement overlays in hot climate regions

Handling and Storage Guidelines

Crumb Rubber Modified Bitumen 50 should be handled following standard hot bitumen safety practices.

  • Use appropriate personal protective equipment (PPE)

  • Store in clean, dry, and well-ventilated tanks or containers

  • Avoid contamination with water or foreign materials

  • Maintain recommended storage temperatures to preserve binder properties

Packaging and Supply Options

CRMB 50 is available in multiple packaging formats to meet different project requirements:

  • Bulk tanker trucks for large-scale infrastructure projects

  • Steel drums for export shipments and smaller volumes

CRMB 50 vs Conventional Bitumen

Unlike standard penetration grade bitumen, CRMB 50 offers enhanced elasticity and resistance to deformation, allowing pavements to withstand higher stresses without cracking or rutting.

CRMB 50 is selected when conventional bitumen reaches its performance limits under heavy traffic and hot climate conditions.
