Description:
Cutback Bitumen, also known as Liquid Bitumen, is a high-quality asphalt binder mixed with a controlled quantity of solvent to reduce its viscosity for easier application. This makes it ideal for cold weather conditions and situations where heating standard bitumen is impractical. Once applied, the solvent evaporates, leaving behind a durable and adhesive bitumen film that ensures long-lasting pavement performance.
With excellent workability, Cutback Bitumen provides superior penetration, adhesion, and waterproofing properties, making it a preferred choice for road construction, priming, and surface dressing applications. Its controlled curing time allows for better bonding with aggregates, enhancing the durability and flexibility of pavements.
Available Grades:
- Rapid Curing (RC): RC-30, RC-70, RC-250, RC-800, RC-3000
- Medium Curing (MC): MC-30, MC-70, MC-250, MC-800, MC-3000
- Slow Curing (SC): SC-70, SC-250, SC-800, SC-3000
