Polymer Modified Asphalt (PMA)

Product Description:

Our Polymer Modified Asphalt (PMA) is a premium hot mix asphalt, enhanced with specially selected polymers added to the bitumen binder. This modification provides superior performance characteristics compared to standard asphalt, including increased resistance to rutting, fatigue cracking, and temperature variations, making it ideal for demanding applications in Malaysia's climate and traffic conditions. Conforms to relevant JKR/MS specifications for PMA.

Key Features:

• Mix Type: Dense-graded or Gap-graded (e.g., SMA-PMA) Hot Mix Asphalt, modified with polymers.
• Layer Type: Typically Wearing Course or Binder Course (specify intended grade, e.g., PMA ACW14, PMA ACB28).
• Binder Type: Polymer Modified Bitumen (PMB).
• Properties: Enhanced rut resistance, improved fatigue life, increased stiffness at high temperatures, better flexibility at low temperatures, enhanced durability.
• Compliance: Manufactured to meet JKR/SPJ/xxxx specifications for Polymer Modified Asphalt.

Ideal for:

• High-traffic highways and major roads.
• Airfield pavements (runways, taxiways).
• Bridge decks and approaches.
• Intersections, bus lanes, and areas prone to heavy braking/acceleration.
• Locations with extreme temperature fluctuations or heavy loads.

Benefits:

• Extended Pavement Life: Significantly increases resistance to common asphalt failures.
• Reduced Maintenance: Lower life-cycle costs due to increased durability.
• Improved Safety: Maintains surface integrity and skid resistance better under stress.
• High Performance: Handles heavy traffic loads and harsh conditions more effectively.

Order our Polymer Modified Asphalt (PMA) for superior pavement performance and longevity!

Important Notes:

• Often specified as PMA combined with a standard mix type (e.g., PMA-ACW14). Specify exact type needed.
• Requires experienced handling and paving procedures due to modified binder properties.
• Pricing is higher than standard asphalt due to polymer cost; typically charged per tonne.
• Delivered hot via insulated tipper trucks.
