Cutback bitumen MC 30 is dissolved of bitumen in solvents of kerosene.
cutback asphalt MC 30
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.
The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily. The cutback agent evaporates from the seal coat, the cutback agent becoming a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat an unwanted long term softening effect may result.
Application of cut back asphalt MC 30:
Cutback agents are 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 is ideal for prime coat and cold applied because of easy uses and no need to thinning and heating.
Cutback bitumen MC 30 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.
The cutback asphalt MC 30 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.
Packing of cutback bitumen MC 30:
Packing of cutback bitumen MC 30 is in new thick steel drum on pallet to prevent any leak inside of container also bulk in bitutainer and tanker.
