Cutback bitumen

Cutback bitumen is a liquid bitumen blend made by dissolving pure bitumen in petroleum solvents (gasoline, kerosene, or diesel). It flows easily at ambient temperatures, eliminating the need for excessive heating. Used in road priming, tack coats, and cold mix asphalt, it offers quick curing (RC, MC, SC grades) and deep penetration. Though cost-effective, its solvent emissions raise environmental concerns compared to emulsified bitumen. Green Vision Group supplies high-quality cutback bitumen compliant with ASTM, ISO, and EN standards for global infrastructure projects.

Cutback Bitumen is a liquid form of bitumen blended with volatile solvents such as kerosene or naphtha to temporarily lower its viscosity. This allows for easier application at ambient temperatures, eliminating the need for extensive heating equipment. Once applied, the solvent evaporates, leaving behind a durable and adhesive bituminous binder. Depending on the evaporation rate of the solvent, Cutback Bitumen is categorized into Rapid Curing (RC), Medium Curing (MC), and Slow Curing (SC) grades.
