MC-250 bitumen is a type of dissolved bitumen. To produce this type, solvent oils such as Kerosene are used in order to change bitumen into dissolved bitumen or liquid pitch, so that, during consumption process, the solvent oil evaporates and the bitumen residue to obtain the desirable adhesion.

Usage

This type of bitumen is most commonly used as an adhesive material between road foundation and asphalt coating, in road construction industries, which include superstructure and foundation.(Nowadays the usage of this type declines because of its replacement with the water base bitumen like bitumen emulsion, which performs better, while eliminating the dangerous environmental impacts.)
