Product Description

Natural Asphalt-R for road constructions, is a naturally occurring hydrocarbon resin engineered to enhance the performance of asphalt and bitumen binders. When blended, it produces permanently stable mixes with no risk of phase separation, ensuring consistent quality during storage, transport, and application.

Natural Asphalt-R is a unique hydrocarbon resin that transforms ordinary asphalt into high‑performance pavement solutions. Permanently stable blends deliver thinner, longer‑lasting roads with exceptional strength, resilience to extreme temperatures, and superior resistance to water damage—helping infrastructure stand the test of time.

Key Technical Advantages

• Binder Reinforcement: Increases stiffness modulus, enabling thinner pavement layers without compromising durability.

• Deformation Resistance: Provides superior rutting resistance under heavy traffic and high loads.

• Thermal Stability: Maintains mechanical performance across extreme temperature ranges, reducing risks of rutting in hot climates and cracking in cold conditions.

• Moisture Protection: Improves adhesion between binder and aggregates, significantly reducing water striping and moisture damage.

Applications

·       Natural Asphalt-R: Ideal for highways, airports, and heavy-duty pavements requiring long service life and reduced maintenance.

• Natural Asphalt-R: Used in bridge decks, industrial flooring, and urban roads where deformation resistance and temperature stability are critical.
