BS group Bitumen SC70 is slow curing (SC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of slow volatility.
Our Cutback Bitumen SC-70 complies with cutback petroleum asphalts of the slow-curing type for use in the construction and treatment of pavements as per ASTM D2028-97 reapproved in 2004.
The SC-70 and SC-250 grade cutback asphalts are very similar to residual refinery products that are used as heavy fuel oils such as bunker C or Number six fuel oils. These SC cutback materials, whether straight run or fluxed with a relatively non-volatile material such as gas oil, are also known as “road oils”.
Typical properties of bitumen SC70
BS group guaranty quality of cutback SC-70 with arrangement of international inspector. By checking quality and quantity of bitumen on each shipment during loading to vessel. Also controlling the production by QC team via batch test report before shipping.
Here are properties of BS group Bitumen cutback SC70 which is classified by ASTM/EN15322:2009.

Applications
This kind of bitumen is suitable to be used in the construction and treatment of pavements as per ASTM D2028-97 reapproved in 2004. Cutback bitumen SC-70 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.
The cutback asphalt SC-70 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.
