Asphalt Cutbacks

Asphalt cutbacks use petroleum solvents for dissolving asphalt cement. The solvents are variously called distillate, diluents, or cutter stock. If the solvent used in making the cutback asphalt is highly volatile, it will quickly escape by evaporation. Solvents of lower volatility evaporate more slowly. On the basis of the relative speed of evaporation, cutback asphalts are divided into three types: rapid curing (RC), medium curing (MC) and slow curing (SC).

Rapid Curing Cutbacks

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

Medium Curing Cutbacks

Medium curing asphalt cement uses medium diluents of intermediate volatility generally in the kerosene boiling point range (MC-30, 70, 250, 800, 3000).

Slow Curing Cutbacks

Slow curing asphalt cement and oils of low volatility generally in the heavy distillate range (SC-70, 250, 800, 3000).
