Cutback bitumen

Cutback bitumen is a blend of bitumen and solvent, designed for ease of working in lower temperatures and to increase durability. It’s used for road construction and maintenance. Classification of cutback bitumen is determined by solvent used and curing time. Three types are RC, MC, and SC, used respectively for surface treatments, prime coats, and tack coats. Cutback bitumen is cost-effective and easy to use. Cutbacks are also used in cases where bitumen cannot be preheated to make asphalt.

Please don't hesitate to ask if you have any questions whatsoever.
