Description of Cutback Bitumen SC-3000
Cutback Bitumen SC-3000 is an SC anionic bituminous product which is primarily employed in road surfacing and surface treatments like chip seals and dust control for unpaved roads. It is produced by blending a heavy industrial solvent (such as black oil or diesel) with pure bitumen, reducing its viscosity and ease of application at low temperatures.
The SC-3000 grade is a specified viscosity, thus for temperate climatic conditions or heavy-duty operations with extended curing times. SC-3000 is a cutback asphalt with approximately 80% of pure asphalt, which exhibits good adhesion and durability.
Manufactured in line with the ASTM D 2026M-15 standard, BS Group’s Bitumen SC-3000 also meets ASTM D2028-97 standards for pavement construction and treatments, re-approved in 2004. With its slow curing characteristic, it is a reliable choice for highway infrastructure applications that require extended setting times and high penetration capability.
Where is Cutback Bitumen SC-3000 used?
Cutback Bitumen SC-3000 is a retarding bitumen used in road construction for continuous granulation and construction of the base, lining, and top of asphalt. It is commonly used in penetrating prime coats and producing patching or stockpile mixtures. The solvent evaporation time of this bitumen is long, making it less used by road construction engineers. It is used to lower the viscosity of bitumen when applied as a primer to the surface of road pavement aggregate base courses or substrates.
Kerosene is used as a bitumen cutback agent at different concentrations according to local conditions and requirements. SC3000 is ideal for prime coat and cold applied applications due to its easy use and no need for thinning and heating. It is also used for waterproofing surfaces, plugging capillary voids, coating, and bonding loose mineral particles.
Cutback Bitumen SC-3000 vs SC-800
The major difference between Cutback Bitumen SC-3000 and Cutback Bitumen SC-800 lies in viscosity and curing time. SC-3000 is more viscous than SC-800 and finds applications in heavy-duty use and higher temperatures where slow curing is desired for better penetration and adhesion. SC-800, however, is thinner in consistency and more easily applied with faster curing and thus finds applications in colder zones or work where faster setting time is required. Both are SC cutbacks but vary in specific applications depending upon the desired workability, ambient conditions, and setting time.
