bitumen MC800

description

Cutback Bitumen MC-800 is a medium curing cutback bitumen consisting of penetration grade bitumen blended with solvent to control its curing time. They type of solvent controls the curing time while the amount determines the viscosity of the cutback bitumen. The solvent usually used to manufacture a medium curing cutback bitumen is kerosene.
The advantage of cutback bitumen have over emulsions is a much higher residual bitumen percent, typically over 80% compares with over 40-65% for bitumen emulsions. The result is more bitumen left on the roadway after curing, for the same volume of binder applied.
Cutback bitumen MC800 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.
Our MC-800 Cutback Bitumen complies with the ASTM D2028-97 standards for construction and treatment of pavements.

applications

Cutback bitumen MC-800 is suitable for primer sealing and can also be used in the manufacturing of asphalt pre-mix. Cutback bitumen are used extensively in sprayed sealing applications, particularly in colder weather where they proved improved initial stone retention due to their lower viscosity. Typically, a single application of the appropriate cutback bitumen is sprayed onto the primed pavement onto which aggregate is laid.
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 MC800 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction. The cutback asphalt MC800 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.

Specification

MC-800 is a cutback bitumen which is a penetration bitumen asphalt blended with kerosene. Kerosene and other petroleum derived products are added as cutback agents reducing the viscosity. MC-800 means solvent is medium caring which express that the solvent will vapor at medium speed. During applying the MC-800 cutback bitumen, the solvent evaporates so the residue demonstrate perfect adhesion. The bituminous cutback asphalt MC-800 is recommended to use for road construction.
Guaranty/warranty of cutback asphalt MC800: ATDM guaranty the quality of cutback MC800 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. ATDM guaranty the quality to meet with ASTM/EN 15322:2009
