BS group Bitumen MC70 is medium curing (MC) cut-back asphalt. Cutback bitumen MC-70 is dissolved of bitumen in solvents of kerosene.
The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. After application, the diluent evaporates, leaving asphalt cement to perform its function.
Cutback bitumen is ideal for prime coat and cold applied. Because of its easy uses and no need to thinning and heating.
Typical properties of bitumen MC70
BS group guaranty quality of cutback MC-70 with arrangement of international inspector. By checking quality and quantity of bitumen on each shipment during loading to vessel. Also controlling the production by QC team via batch test report before shipping.
Here are properties of BS group Bitumen cutback MC70 which is classified by ASTM/EN15322:2009.

Applications
Cutback bitumen MC70 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.
In addition, cutback asphalt MC-70 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.
This kind of bitumen is suitable to be used in Roofing – As a waterproofing membrane and as an adhesive to stick chippings onto a flat, horizontal roof to minimize the effects of weathering from the sun.
