Cutback Bitumen SC-800 Description
Cutback Bitumen SC-800 is an asphalt cement that has a solvent or distillate such as gasoline, diesel fuel, kerosene, or naphtha added to make the asphalt liquid at ambient temperatures and improve its ability to coat aggregates. Two letters followed by a numerical digit designate or name a cutback asphalt.
Cutback asphalt can contain between 12 and 40 percent distillate. The high demand for the distillates to be used in energy applications and ever-increasing air quality regulations have caused a steady decline in the use of cutback asphalt.
The SC liquid asphalt may be obtained by fluxing an asphalt cement with a less volatile distillate such as gas oil. 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”.
Cutback Asphalt SC-800 Applications
Current common uses are in penetrating prime coats and in producing patching or stockpile mixtures. Cutback asphalt used in mixing with aggregate will usually contain an adhesion agent to assist in the coating of the aggregate surface.
Cutback agents are used to lowering 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 for thinning and heating.
Cutback bitumen SC-800 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.
The cutback bitumen SC-800 applying to waterproof of surfaces plug capillary voids, coat, and bond loose mineral particles.
Packing of Cutback Bitumen SC-800
This cutback bitumen bulk in the tanker and also in new steel and thick drum on the pallet to prevent all leak inside of the container.
