Cutback Bitumen – Slow Curing

SC-30, SC-70, SC-250, SC-800 and SC-3000


Slow Curing (SC) asphalt cement and oils of low volatility generally in the heavy distillate range (SC-30, SC-70, SC-250, SC-800 and SC-3000). 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.

Slow Curing (SC) Cutback asphalts are often called road oils and are used primarily in road-mixing and dust-laying applications. This term originated in earlier days when asphalt residual oil was used to give roads a low-cost, all-weather surface. SC Cutback asphalts are also used for stockpile patching mixes, plant-mixed with graded aggregates and occasionally for priming.

Tiger Cement Limited has the capability to Export and Supply the different Grades of Slow Curing Cutback Bitumen in compliance with National and International standards.
