Reduction in viscosity of bitumen aids construction of seal coats in road pavements as softened mixture wets chips more easily.
Furthermore cutback agent evaporates from seal coat, it becoming a negligible component of 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.
Cutback bitumen SC250 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction. In addition the cutback asphalt SC250 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 and no need to thinning and heating.
Packing of cutback bitumen SC250 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.
PUB-LTD guaranty the quality of cutback SC250 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
