Cutback Asphalt MC 800
Cutback bitumen MC 800 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 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 Cutback Bitumen MC 800:
Cutback bitumen MC-800 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction. Furthermore cutback asphalt MC-800 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.
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.
We use Kerosene as a bitumen cutback agent at different concentrations according to local conditions and requirements.
Cutback bitumen is ideal for prime coat. Also it cold applied because of easy uses and no need to thinning and heating.
Packing of Cutback Bitumen MC 800:
Packing of cutback bitumen MC-800 is in new thick steel drum. This drums are on pallet to prevent any leak inside of container. Also bulk in bitutainer and tanker is possible.
