CMA (Cuplump Modified Asphalt), adhering to JKR specifications, incorporates cuplump (a form of natural rubber) to modify the asphalt binder. This results in enhanced elasticity, improved resistance to cracking, and a more durable pavement, especially suited for the Malaysian climate.
Key Features:
JKR Compliant: Meets relevant JKR Standard Specification for Road Works clauses.
Cuplump Modification: Uses cuplump to alter the asphalt's properties.
Increased Elasticity: Greater ability to return to its original shape after deformation.
Improved Crack Resistance: More resistant to thermal and fatigue cracking.
Enhanced Durability: Provides a longer-lasting pavement.
Ideal for:
Roads in high-temperature environments.
Pavement overlays.
Areas prone to cracking.
Specific applications determined by the relevant JKR specification clause.
Benefits:
Extended Pavement Life: Cuplump improves durability and reduces maintenance.
Reduced Cracking: Increased elasticity minimizes cracking in hot climates.
Improved Performance: Enhanced flexibility provides a more robust pavement.
JKR Compliance: Meets JKR standards for cuplump-modified asphalt.
Important Notes:
Always refer to the specific JKR specification clause for detailed requirements.
Requires specialized mixing and laying procedures.
