Cutback MC70
Bitumen cutback MC70 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluents or cutter of ... Read More
Medium Curing (MC) asphalt cement uses medium diluents of intermediate volatility generally in the kerosene boiling point range (MC-30, MC-70, MC-250, MC-800 and MC-3000).
MC bitumen is widely used in tack coats, fog seals, slurry seals, and stabilizers. Mc grades have a high prioritized place in the Kenya market. This bitumen grade is widely applied in many countries, especially East African countries such as Kenya and Tanzania.
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 Bitumen 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.
