General description of Cutback Bitumen MC-250
Cutback bitumen MC-250 is dissolved of bitumen in solvents of kerosene. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen.
The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. Cutback MC-250 is used in the road maintenance industry where it is used as a prime coat of the base course prior to placing the bituminous surface course.
Cutback MC-250 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 the consumption process, the solvent oil evaporates and bitumen residue to obtain the desired adhesion. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen.
MC-250 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluents or cutter of medium volatility. The diluents temporarily reduce the viscosity of the asphalt cement for ease of handling and application.
Our MC-250 Cutback Bitumen complies with cutback petroleum asphalts of the Medium-Curing type for use in the construction and treatment of pavements as per ASTM D2028-97 reapproved in 2004.

Application of Cutback MC-250
Current common applications are in penetrating prime coats and in producing patching or stockpile mixtures. This type of Bitumen is most commonly used as an adhesive material between road foundation and asphalt coating, in the road construction industry which includes superstructure and foundation. Also, Cutback Asphalt MC-250 is suitable for primer sealing and can also be used in the manufacturing of asphalt pre-mix.
