CRMB-50: Balanced Flexibility & Durability for Urban and Rural Roads
Designed for moderate traffic loads and variable climates, IS 15462:2004 compliant.
What is CRMB Bitumen?
CRMB-50 is a crumb rubber modified bitumen engineered for projects that require both flexibility and strength under moderate traffic loads. Formulated by blending high-quality base bitumen with recycled rubber from end-of-life tires, CRMB-50 provides excellent crack resistance and temperature control, making it suitable for diverse climates.
This eco-conscious grade is commonly used in rural roads, secondary roads, and urban streets, where cost-effectiveness and performance must go hand in hand. With its balance of durability and adaptability, CRMB-50 enhances hot mix asphalt for reliable, long-lasting surfaces.
It delivers unmatched durability for
- High-traffic highways
- Eco-Conscious Infrastructure Projects
- Hot Mix Asphalt
- Airport runways
- Port pavements
- Industrial zones
Key Specifications
- Penetration @ 25°C: 70 max (ASTM D5)
- Softening Point (°C): 55 min (ASTM D36)
- Elastic Recovery at 15°C: ≥ 50% (ASTM D6084)
- Flash Point (°C): ≥ 220 (ASTM D92)
- Viscosity at 150°C: 1–3 Poise (ASTM D4402)
- Compliance: IS 15462:2004
Compliance
- IS 15462 | NFPA 30 | ASME BPVC
Why CRMB-50 Bitumen
Stands Out
1.Balanced Performance
- Combines durability and flexibility, ideal for variable traffic conditions.
2.Crack Resistance
- Superior elasticity reduces cracking in temperature fluctuations.
3.Eco-Conscious Solution
- Made with recycled rubber, contributing to sustainability.
4.Thermal Stability
- Controls softening and deformation in moderate climates.
5.Proven Safety
- Flash point ≥ 220°C ensures secure handling, storage, and transport.
