Cutback Bitumen MC-70
Cutback Bitumen MC-70 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of medium volatility.
The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. After application the diluent evaporates, leaving asphalt cement to perform its function. Petrochemical Trade Cutback MC-70 conforms to the specifications of ASTM D2127. (Medium-Curing Asphalt) or AASHTO M82a) Roofing – As a waterproofing membrane and as an adhesive to stick chippings onto a flat. Horizontal roof to minimize the effects of weathering from the sun. b) Damp-Proof Courses – Use as damp-proof membranes. in concrete floors particularly for small repairs or where extensions key-in to existing structures.
General Description of Cutback Bitumen MC-70
Cutback Bitumen MC70 dissolve 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 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.
Cutback agent also evaporates seal coat, cutback agent becoming a negligible component of seal coat a few months after application. If significant amounts of cutback agent remain in seal coat an unwanted long term softening effect may result.
Uses of cut back asphalt MC-70
Cutback bitumen MC70 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimpose treatment of construction.
In addition cutback asphalt MC-70 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.
Cutback agents use 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. Furthermore we use Kerosene as a bitumen cutback agent at different concentrations according to local conditions and requirements.
Meanwhile Cutback bitumen is ideal for prime coat and cold apply. Because of its easy uses and no need to thinning and heating.
Packing of Cutback Bitumen MC-70
Packing of cutback bitumen MC70 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.
