Bitumen RC70 is rapid curing liquid packed in drum and IBC tank
General description of cutback asphalt RC 70
Bitumen RC70 is dissolved of bitumen 60/70 in ultra light solvents. 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.Uses of cut back asphalt RC 70
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. Bitumen RC70 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction. The bitumen RC70 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.Packing of cutback bitumen RC70
Packing of bitumen RC70 is in new thick steel drum on pallet to prevent any leak inside of container also bulk in bitutainer and tanker.Analysis of bitumen RC70
