General description of Cutback Bitumen SC70
Cutback Bitumen SC70 is dissolved of bitumen in solvents of kerosene. many countries derive kerosene and other volatile petroleum products and add as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. Mixture obtained, called cutback bitumen.
Reduction in viscosity of bitumen aids construction of seal coats in road pavements as softened. Mixture wets the chips more easily.
Furthermore 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 SC70
Cutback bitumen SC-70 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 SC-70 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. Also we use Kerosene as a bitumen cutback agent at different concentrations according to local conditions and requirements.
Cutback bitumen is ideal for prime coat and cold applied because of easy uses. Also no needs to thinning and heating.
Packing of cutback bitumen SC-70
Packing of cutback bitumen SC-70 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.
Guaranty/warranty of cutback asphalt SC70
PUB-LTD guaranty the quality of cutback SC-70 with arrangement of international inspector. By checking quality and quantity of the bitumen on each shipment during the loading to vessel. Also controlling the production by QC team via batch test report before shipping. PUB-LTD guaranty the quality to meet with ASTM/EN15322:2009
