DESCRIPTION

BNA Cutback Grade Bitumen is normally used in spraying and in some mixing application. Cutback Bitumen is penetration grade bitumen blended with a solvent such as kerosene, white spirit, gasoline and naphtha controlling the curing time. Cutbacks are divided into 2 types, Rapid Curing (RC) and Medium Curing (MC) depending on the solve used. Commonly used for road and pavement construction and maintenance. Cutback MC 30 is blended with a solvent such as Kerosene, a medium curing petroleum cutter.

APPLICATION

BNA Cutback MC 30 containing 50% Bitumen, is commonly used as a Prime Coating. The process of priming involves applying a low viscosity binder to a prepared but usually unbound aggregate base. It is intended to be absorbed by the top layers of the base and provide a surface which is more easily wetted by a following bituminous covering. Cutback bitumen which is suitable for priming is also used for Tack-Coating. This is applied to an underlying surface to aid with the adhesion of the following asphalt layer.
