Rapid Curing

Rapid Curing (RC) asphalt cement is a combination of light diluents of high volatility, generally in the gasoline or naphtha boiling point range (RC-30, RC-70, RC-250, RC-800 and RC-3000), and asphalt cement.

Cutback bitumen Rapid Curing, RC, is a petrochemical mixture of solvent as naphtha or gasoline and bitumen.

The degree of liquidity developed in each case depends principally on the proportion of solvent to asphalt cement. To a minor degree, the liquidity of the cutback may be affected by the hardness of the base asphalt from which the cutback is made. The degree of fluidity results in several Grades of Cutback asphalt—some quite fluid at ordinary temperatures and others somewhat more viscous. The more viscous grades may require a small amount of heating to make them fluid enough for construction operations.
