Properties & Benefits
Crumb rubber modified bitumen (CRMB) is produced by blending conventional bitumen with crumb rubber, which is derived from ground scrap rubber from used trucks or automobile tires. Following are the properties of CRMB:
Enhanced Elasticity and Flexibility
CRMB is more flexible than conventional bitumen, allowing it to absorb and disperse stresses from traffic loads and temperature changes
Improved Resistance to Rutting and Cracking
Higher viscosity and elasticity make CRMB highly resistant to rutting and thermal or fatigue cracking, extending pavement life
Better Adhesion
CRMB exhibits stronger adhesion to aggregates, thereby improving pavement durability
Temperature Performance
It performs well across a range of climates, with different grades (e.g., CRMB 50, 55, 60) tailored for cold, moderate, and warm climates respectively
Environmental Advantage
Using recycled tire rubber helps reduce landfill waste and promotes sustainable construction practices
Economic Benefits
Though initial costs may be higher, CRMB reduces maintenance and repair frequency, lowering life-cycle costs of pavements
Applications
CRMB is a modified bitumen binder enhanced with crumb rubber from recycled tires, offering superior elasticity, flexibility, and resistance to rutting and cracking compared to conventional bitumen. Following are the applications of CRMB:
High-traffic roads, highways, junctions, heavy-duty pavements, seaport roads, and airport runways
Both new road construction and operations & maintenance projects where durability and resistance to deformation are critical
