Bitumen RC-70 is a rapid-curing cutback asphalt, blending penetration-grade bitumen with a fast-evaporating solvent like naphtha. It features a kinematic viscosity of 70–140 cSt at 60°C and complies with ASTM D2028 standards. Ideal for prime and tack coats, surface dressing, and cold mix applications, it ensures quick bonding and is supplied in steel drums or bulk containers. The solvent evaporates rapidly, leaving a durable asphalt residue.
