General description of cutback asphalt MC 3000
Bitumen MC 3000 is mostly used as the tack coat in grit seals, sand seals, Otta seals and single seats for lightly trafficked roads. Constructed during winter.Bitumen MC 3000 is a high viscosity cutback bitumen with a high binder content. The cutter ensures proper wetting of the cover aggregates whilst depositing a film of bitumen to provide adhesion to the base.
how to use bitumen MC3000
1. Apply with a calibrated distributor at a binder spray temperature of 135°C and a minimum road surface temperature of 15°C and rising.
2. Special care must be taken whilst heating, as Bitumen MC 3000 contains flammable cutters which have a flash point of >40°C.
3. Curing time will depend mostly on the weather conditions.
Differences of bitumen MC 3000 and MC30
The composition of MC 30 is generally a mixture of 58% penetration grade 80/100 and 42% kerosene. While, MC3000 is composed of 85% penetration grade 80/100 and 15% kerosene. MC 30 has the lowest viscosity among all grades of medium curing and MC 3000 has the highest viscosity.
Uses of cut back asphalt MC 3000
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 MC3000 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.
The cutback asphalt MC3000 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.
Packing of cutback bitumen MC3000
Packing of cutback bitumen MC3000 is in new thick steel drum on pallet to prevent any leak inside of container also bulk in bitutainer and tanker.
Guaranty/warranty of cutback asphalt MC3000
ATDM guaranty the quality of cutback MC3000 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
