What is MC250 Cutback Bitumen ?

Cutback Bitumen MC250 is a specialized form of bitumen, modified with a medium-curing solvent like kerosene to lower its viscosity for better application and handling. Comprising 67% bitumen, this product boasts a viscosity range between 250 to 500 CST, making it ideal for road construction. It is extensively used as a prime coat to enhance the adhesion between the underlying surface and subsequent bituminous lay
