Cutback Bitumen SC70

General description of cutback asphalt SC70

Cutback bitumen SC70 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.

Uses of cut back asphalt SC70

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 SC70 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.

The cutback asphalt SC70 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.

Packing of cutback bitumen SC70

Packing of cutback bitumen SC70 is in new thick steel drum on pallet to prevent any leak inside of container also bulk in bitutainers and tanker.

Guaranty/warranty of cutback asphalt SC70

GLB guaranty the quality of cutback SC70 with arrangement of international inspector to check quality and quantity of the bitumen on each shipment during the loading to vessel and controlling the production by QC team via batch test report before shipping. GLB guaranty the quality to meet with ASTM/EN 15322:2009
