Cutback MC250

Bitumen cutback MC250 is a cutback bitumen which is a penetration bitumen asphalt blended with kerosene. Kerosene and other petroleum derived products are added as cutback agents reducing the viscosity.

During applying the MC-250 cutback bitumen, the solvent evaporates so the residue demonstrates perfect adhesion. The cutback asphalt MC250 is recommended to use for road construction. MC 250 means solvent is medium caring which express that the solvent will vapor at medium speed.


Application of Bitumen Cutback MC250

cutback MC250 is used to lower the viscosity of bitumen when it is applied as a primer to the surface of a road pavement aggregate base course or substrate. Kerosene is used as a bitumen cutback agent at different concentrations according to local conditions and requirements.

The cutback bitumen mc250 is ideal for prime coat and cold applied because of easy uses and no need to thinning and heating.
