Description
General description of Cutback Bitumen MC30
Cutback Bitumen Medium Curing (MC)30 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.
The reduction in viscosity of bitumen aids construction of seal coats in road pavements as softened mixture wets the chips more easily.
Cutback agent evaporates from seal coat, cutback agent 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.
Uses of Cutback Asphalt MC-30
Cutback bitumen MC30 also 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 MC-30 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 also is ideal for prime coat and cold applied. Because easy uses and no need to thinning and heating.
Guaranty/warranty of cutback asphalt MC-30
PUB-LTD guaranty quality of cutback MC-30 with arrangement of international inspector. By checking bitumen quality and quantity on each shipment during loading to vessel. Also controlling production by QC team via batch test report before shipping. PUB-LTD guaranty quality to meet with ASTM/EN15322:2009
Packing of Cutback Bitumen MC-30
Packing of cutback bitumen MC-30 is in new thick steel drum. This drums are on pallet to prevent any leak inside of container also bulk in bitutainer and tanker.
