CRMB
Crumb Rubber Modified Bitumen — enhanced elasticity and fatigue resistance.
Engineered for performance, dispatched with confidence.
CRMB is manufactured by digesting finely ground crumb rubber from end-of-life tyres into paving bitumen at controlled temperature and shear. The result is a modified binder with markedly superior elastic recovery, fatigue life and resistance to permanent deformation.
We supply CRMB 55 and CRMB 60 grades as per IS:15462. Both are specified by NHAI, MoRTH and major state PWDs for heavy-traffic National Highways, expressway overlays and freight corridors operating in high temperatures.
Beyond performance, CRMB delivers a measurable sustainability benefit by diverting waste tyre rubber from landfill and incineration — an industrially proven circular use of recycled material.
Applications
- National Highway wearing courses
- Expressway and freight-corridor overlays
- Heavy-axle truck route pavements
- Hot-climate high-traffic zones
- Bridge approaches and toll plazas
Key Benefits
- Better fatigue and reflective-crack resistance
- Improved skid resistance and rut control
- Reduced thermal deformation
- Extended pavement service life
- Sustainable use of recycled tyre rubber
