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 high-quality, high-viscosity bitumen solution primarily used in demanding road construction and maintenance projects. This product is particularly effective for large-scale applications where durability and strong adhesion are critical. Due to its reduced viscosity, it facilitates easier application, particularly in colder climates or regions with lower temperatures, where it can be challenging to work with traditional, higher-viscosity bitumen. SC-3000 is commonly used as a primer to enhance the bonding between the road foundation and asphalt layers, ensuring a solid, long-lasting foundation for road pavements.
Additionally, Cutback SC-3000 is highly effective in the production of seal coats, providing a smooth and durable surface that enhances the performance and longevity of roads. Its ability to penetrate and bond with road aggregates makes it ideal for use in patching mixtures and stockpiling mixtures for future repairs. SC-3000 is also used in spraying applications, where its consistent application ensures even coverage and a high-quality finish. With its superior adhesion and flexibility, SC-3000 is an essential material for large-scale road construction, maintenance, and repair projects, ensuring long-lasting results and enhanced road performance.
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.
