CRMB — Crumb Rubber Modified Bitumen
Waste-tyre crumb rubber modified binder (IS 15462 / IS 17079)
What is CRMB — Crumb Rubber Modified Bitumen?
Crumb Rubber Modified Bitumen (CRMB) is bitumen modified with crumb rubber recovered from waste tyres, improving elasticity, fatigue life and temperature susceptibility while consuming a waste material. Common grades include CRMB 50, CRMB 55 and CRMB 60.
CRMB delivers much of the performance of PMB, often at lower cost, and supports the circular economy by reusing scrap tyre rubber. It is widely used on highways and heavy-traffic urban roads.
Benefits
- Cost-effective performance — strong results, usually cheaper than PMB
- Uses waste tyres — consumes crumb rubber, an environmental plus
- Better elasticity & life — improved fatigue and rut resistance
- Temperature tolerant — performs across hot Indian summers
- Standard grades — CRMB 50 / 55 / 60 to suit climate zones
Applications & buyers
- National & state highways and heavy-traffic city roads
- Hot-mix wearing and binder courses
- Regions prioritising waste-tyre reuse / green procurement
- Overlays and strengthening of existing pavements

Cost & ROIIndicative only — actual figures depend on capacity, location, raw-material price and utilisation. Contact us for an exact DPR.
Figures are for plant supply only — land and working capital are separate — and reflect a batch / semi-continuous build. Fully-continuous, automated, premium-spec production plants cost more (roughly ₹0.8–1.2 Cr per TPD). Your exact cost is fixed in a site-specific DPR.
Best Indian states for this plant.
Hot climates favour CRMB; waste-tyre availability; cost-sensitive highway works.
How much land you'll need.
Indicative plot size by capacity — we lock the exact figure to your layout and feedstock plan during feasibility.
Indicative footprint per capacity tier. Actual plot size depends on layout, feedstock storage, effluent/ZLD provisions, future expansion and statutory setbacks — finalised in the feasibility / DPR stage.
