Crumb Rubber Modified Bitumen
CRMB is a blend of selected grades of Bitumen and modifier. The rubber modifier used, balances the required visco-elastic balance of the bitumen binder, which improves the resistance to thermal and low temperature cracking.
CRMBhas good adhesion to different types of aggregates which therefore reduces cracking, deformation, etc.
CRMB meets the specification of IS:15462 of 2004.
CRMB, a meticulously crafted amalgamation of meticulously selected Bitumen grades and modifiers, stands as a testament to innovation in road construction. Infused with a carefully chosen rubber modifier, CRMB achieves a delicate equilibrium in the visco-elastic properties of the bitumen binder, thereby fortifying its resistance against thermal fluctuations and low-temperature cracking, ensuring enhanced pavement durability and longevity.
Advantages Of Using CRMB
- Cost effective
- Improves resistance to cracking, resulting in stronger and more durable overlays for corridors in the areas of extreme climatic conditions and heavy traffic loads
- Reduces deformation on road at elevated temperature
- Achieves more viscosity and elastic recovery as compared to conventional bitumen
- Better adhesive property
- Higher stability and flexibility
Application Of CRMB
- Construction, maintenance and renewal of roads with heavy traffic
- Runways and pavements of airports
- Surfacing at flyovers, junctions, etc.
