Crumb Rubber Modified Bitumen

TIKI CRMB is a blend of selected grades of bitumen and crumb rubber modifier. The modifier restores the required visco-elastic balance of the Bitumen binder, which improves binder resistance to any form of permanent deformation while maintaining high resistance to fatigue, thermal and low temperature cracking. Using TIKI CRMB, the maintenance free life of pavement will increase one and half to two times as compared to roads built using unmodified neat bitumen binders. TIKI CRMB has good adhesion to different types of aggregates which therefore reduce rutting, cracking, deformations, etc. TIKI CRMB meets the performance- based specification of IRC: SP 53-2002.

Advantages:

• Excellent Resistance to Thermal and low temperature cracking.
• Superior resistance to any form to permanent deformation.
• Better adhesion between aggregate and binder.
• Overall improved performance in extreme climatic conditions.
• Higher fatigue life of mixes.
• Highly flexible and stability.
• Cost effective.
