Cutback Bitumen RC-800 – High-Performance Road Binder from Pars Bitumen

 

 

What is Cutback Bitumen RC-800?

Cutback Bitumen RC-800 is a rapid-curing (RC) grade of liquid bitumen manufactured by blending penetration-grade bitumen with a suitable petroleum solvent, typically naphtha or gasoline. This formulation reduces the viscosity of bitumen, making it easy to handle and apply at ambient temperatures. Once applied, the solvent evaporates quickly, leaving behind a durable and adhesive film of pure bitumen that binds aggregates firmly.

Applications of RC-800

Cutback Bitumen RC-800 is widely used in road construction and maintenance due to its rapid setting characteristics. Typical applications include:

Surface dressing for roads and highways

Prime coating before laying asphalt

Tack coating between pavement layers

Cold mix asphalt production

Patching and repair works

Its quick curing property makes RC-800 especially effective in regions with moderate to warm climates where fast drying and strength development are essential.
