Bitumen cutback MC70 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluents or cutter of medium volatility. Cutback MC-70 use in the road maintenance industry where it is used as a prime coat of the base course prior to placing the bituminous surface course.
The diluents temporarily reduce the viscosity of the asphalt cement for ease of handling and application.
Application of Bitumen Cutback MC70
Cutback bitumen MC70 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.
The cutback asphalt MC70 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.
Bitumen MC70 Specification
