Crumb Rubber Modified Bitumen (CRMB)

Crumb Rubber Modified Bitumen (CRMB) is a globally recognized and economically efficient solution that significantly enhances the performance of conventional bitumen used in asphalt production for road development projects.

This innovative product is produced by modifying pure bitumen with recycled tires and specialized additives. The modification process can increase the service life of roads by up to five times, compared to traditional bitumen.

HJ OIL provides three grades of CRMB (CRMB 60, CRMB 55, CRMB 50), tailored for different climate conditions and road networks:

• Warm Climate → CRMB 60

• General Climate → CRMB 55

• Cold Climate → CRMB 50

  

 Key Benefits of CRMB by HJ OIL

• Longer Road Lifetime: Extends the durability of asphalt pavements up to five times compared to conventional bitumen.

• Lower Maintenance: Reduces maintenance costs significantly over the lifecycle of the road.

• Sustainability: Reuses end-of-life tires, contributing to environmental protection and waste reduction.

• Safety and Comfort: Provides smoother and quieter roads, enhancing driving comfort and reducing traffic noise.

• High Flexibility: Minimizes cracking in cold climates and resists deformation under heavy traffic in warm climates.

• Eco-Friendly Solution: Supports recycling initiatives and reduces landfill waste.

  

 Applications (Uses)

• Highways and Expressways – ideal for heavy traffic conditions requiring durability.

• Airport Runways and Taxiways – ensures stability under extreme loads and temperature variations.

• Urban Roads and Bus Lanes – reduces noise and enhances ride comfort.

• Roundabouts and Intersections – where resistance to rutting and permanent deformation is critical.

• Stone Mastic Asphalt (SMA) Mixes – improves strength and flexibility of road surfacing.

• Porous Asphalt Applications – enhances drainage, reduces water accumulation, and increases road safety.

 Technology and Performance

HJ OIL CRMB is based on a unique stabilizing technology ensuring:

• Homogeneity, stability, and consistency of binder properties across the supply chain.

• Improved elasticity and resistance to temperature susceptibility.

• Enhanced adhesion between binder and aggregates.

• Superior Elastic Modulus for better performance under heavy traffic and high pavement temperatures.

• Increased fatigue life under repeated heavy loading conditions.
