CRMB (CRUMB RUBBER MOTIFIED BITUMEN)
CRMB - Crumb
rubber modified bitumen is useful and having good impact towards lifeline of
the roads flexible pavement with asphalt concrete is wide used all over the
world. It is processed by blending chemically crumb rubber with normal bitumen
which acts as a binder for aggregates is a very important ingredient which
enhances the durability life of the roads.
Specification of CRMB
as per IS 15462:2004
Multiple advantages of CRMB:
1. Higher resistance to deformation at higher temperature.
2. Lower penetration gives additional strength to roads.
3. Better adhesion and cohesion
4. Reducing damage caused by water
5. Resistance to cracking under stress
These
superb characteristics make CRMB a better solution of road pavement which
increases the life by 2-3 times higher than the conventional bitumen and is Environment Friendly.
