Cutback Bitumen

Cutback bitumen is a petroleum product produced by diluting bitumen in petroleum hydrocarbon (Kerosene). The aim is to decrease the viscosity and to increase the penetration of bitumen on asphalt surface. In comparison with bitumen, cutback bitumen is sprayed on different layers of roads in a notably lower temperature. Once the solvent is evaporated, the remaining bitumen equals with penetration bitumen in terms of hardness. 

Cutback bitumen is categorized in 3 groups, according to their curing time:

Rapid Curing (RC)

Medium Curing (MC)

Slow Curing (RC)
