Asphalt bleeding, cracking & early rutting of asphalt pavements due to different atmospheric temperatures and heavy traffic flow are the focal reasons to necessitate a better material that stays along with the varying modalities.
CRMB is a unique blend of Bitumen, Crumbed Tyre Rubber, compatibility oils and other additives. CRMB manufactured by ART is a special grade road surfacing binder with extra ordinary performance properties achieved by addition of specialty chemicals. It is designed to conform IS:15462 specifications & is licensed ISI mark by the Bureau of Indian Standards.
Selection of CRMB grade for various temperature zones.
PMB is a unique blend of Bitumen and plastomeric or elastomeric polymers. These polymers, when added in a specific quantity, provide excellent improvement into the properties of the mix. The modification becomes permanent in nature and is not simply mixed with the Bitumen but, it reacts chemically to provide a stable, more resilient pavement binder with excellent properties ideal to be used in hot mix plants. Modified Bitumen manufactured by ART is available in the grades conforming to IS:15462
Selection of PMB grade for various temperature zones.
Low glass transition
Sufficient stiffness for dimension stability
Excellent elastic recovery
Reduced structural thickness of pavement
Improved adhesion properties
Anti-stripping properties to suit damp climates
Reduced life cycle cost of pavement
