Cutback Bitumen (Medium & Rapid Curing)
High-Performance Bituminous Binder for Flexible & Cold Applications
Cutback Bitumen is a specially formulated bituminous binder produced by blending penetration grade bitumen with controlled amounts of petroleum solvents to reduce viscosity for improved workability at lower temperatures. It is designed for applications where heating facilities are limited or where superior penetration and adhesion to surfaces are required.
Product Types
Rapid Curing (RC) Cutback Bitumen
Rapid curing grades contain highly volatile solvents, allowing quick evaporation after application.
Ideal for:
- Surface dressing
- Tack coats
- Spray sealing
- Patchwork repairs
- Prime coats in fast-track projects
Advantages:
- Fast setting time
- Quick bonding to aggregates
- Reduced construction downtime
- Efficient for time-sensitive projects
Medium Curing (MC) Cutback Bitumen
Rapid Curing (RC) Cutback Bitumen
Rapid curing grades contain highly volatile solvents, allowing quick evaporation after application.
