General Information of Cutback Bitumen RC-800
Cutback asphalt is a type of asphalt cement mixed with a solvent or distillate, such as gasoline, diesel fuel, kerosene, or naphtha. This combination makes the asphalt liquid at ambient temperatures, thereby enhancing its ability to coat aggregates effectively. Interestingly, two letters followed by a numerical digit designate or name a cutback asphalt.Composition and Properties
Cutback asphalt contains between 12 and 40 percent distillate. However, due to the high demand for distillates in energy applications and stricter air quality regulations, the use of cutback asphalt has steadily declined. When gasoline or naphtha acts as a fluxing agent, the product becomes “rapid curing” (RC) cutback asphalt. Moreover, up to 45 percent distillate is permissible in manufacturing RC-800 cutback asphalt.Production Standards
At Gold Bitumen Co., we produce Cutback Bitumen RC-800, which complies with ASTM D2028-97 standards for rapid-curing petroleum asphalts. This product suits pavement construction and treatment. Moreover, Cutback Grade Bitumen is commonly used in spraying and mixing applications. Penetration grade bitumen blends with solvents like kerosene, white spirit, gasoline, and naphtha to control curing time. Additionally, petroleum-grade bitumen, manufactured through fractional/vacuum distillation of crude oil, forms the base material.Uses of Cutback Asphalt RC800
Cutback agents reduce bitumen viscosity, making it ideal as a primer for road pavement aggregate base courses. Kerosene serves as a common cutback agent, adjusted to local conditions and project requirements. Additionally, cutback bitumen is perfect for prime coats and cold applications because it requires no thinning or heating. Consequently, RC800 integrates asphalt into non-asphalt-based surfaces, preparing them for further construction treatments. Furthermore, it waterproofs surfaces, plugs capillary voids, and bonds loose mineral particles effectively.Packing of Cutback Bitumen RC800
Cutback Bitumen RC800 is packaged in thick steel drums placed on pallets to prevent leaks. Besides, it is also available in bulk, transported via bitutainers and tankers for large projects.Guarantee/Warranty of Cutback Asphalt RC800
Gold Bitumen ensures the quality of Cutback RC800 through international inspections during vessel loading. Additionally, the QC team conducts batch tests before shipment to verify product standards. As a result, our products meet ASTM/EN 15322:2009 requirements.Technical Specifications of Cutback Bitumen RC800
