Cutback Bitumen — Composition, Uses, and Advantages | Pars Bitumen

 

What is Cutback Bitumen?

Cutback Bitumen is a type of bitumen whose viscosity has been reduced by adding a solvent such as kerosene, naphtha, or diesel. This modification allows the bitumen to be easily applied at lower temperatures, making it an ideal binder for road construction, surface dressing, and maintenance applications where heating facilities are limited.

At Pars Bitumen, one of the leading bitumen manufacturers in Iran, we produce high-quality Cutback Bitumen designed to perform effectively in diverse climates and project conditions.

Types of Cutback Bitumen

Cutback Bitumen is classified based on the rate of evaporation of the solvent used. The main types are:

1. Rapid Curing (RC) – Prepared by mixing bitumen with volatile solvents like naphtha or gasoline. RC grades are ideal for surface dressing and patching.

2. Medium Curing (MC) – Made with kerosene as the solvent, used for premix works and road construction where gradual curing is required.

3. Slow Curing (SC) – Uses diesel or similar heavy oils. SC grades are best suited for priming and mixing with aggregates at ambient temperatures.

 

Pars Bitumen manufactures all major grades of Cutback Bitumen (RC, MC, SC) following international specifications such as ASTM D2026 / D2027 / D2028.

Applications of Cutback Bitumen

Cutback Bitumen is widely used in:

Surface dressing for roads and highways

Prime coat applications on granular bases

Cold mix asphalt production

Crack sealing and patching work

Maintenance of pavements and rural roads

Thanks to its fluidity at ambient temperature, Cutback Bitumen offers excellent adhesion between aggregates and base layers, ensuring long-lasting pavement performance.
