CutBack Bitumen

MC 30 Cutback Bitumen is a blend of penetration grade bitumen and slow curing petroleum flux.

MC 30 is mainly used for priming newly constructed, crushed stone or natural gravel base courses prior to surfacing. It can also be used for prime sealing to give adequate protection of the pavement for periods of up to 6 to 12 months. The low viscosity of the product makes it ideal for use in the manufacture of pre-mix asphalt used in patch work.

This product is blended to a low viscosity to ensure that it penetrates the top 10mm of the base with the aid of the cutter, whilst depositing a thin film of bitumen on the surface to provide adhesion between the base coarse and the new surfacing.
