Cutback bitumen RC-250 is a rapid-curing asphalt used in road construction and pavement treatment. It contains 65% bitumen and is black in color. The diluent reduces the viscosity of the asphalt cement, making it easy to handle and apply. The mixture aids in the construction of seal coats in road pavements. Cutback RC-250 can be exported to various regions in East Asia, such as China, Malaysia, Thailand, Taiwan, Vietnam, Philippines, Indonesia, and Cambodia. Additionally, it can also be exported to certain African countries, including Congo, Djibouti, and Rwanda.

Description of Cutback Bitumen RC-250

Cutback Bitumen RC-250 is Rapid curing (RC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of rapid volatility. Our Cutback Bitumen RC-250 complies with cutback petroleum asphalts of the rapid-curing type for use in the construction and treatment of pavements.

Cutback Bitumen RC-250 is a rapid curing cutback bitumen that contains 65% bitumen, is black in color, and is manufactured strictly as per ASTM D 2028M standard. The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. After application, the diluent evaporates, leaving asphalt cement to perform its function. RC-250 bitumen viscosity is between 250-500 CST.

Cutback Bitumen RC-250 is dissolved bitumen in solvents of gasoline. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen.

The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily. The cutback agent evaporates from the seal coat, the cutback agent becomes a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat, an unwanted long-term softening effect may result.

Application of Cutback Bitumen RC-250

Cutback bitumen RC-250 is a rapid-curing type, meaning the solvent evaporates quickly, allowing the bitumen to harden relatively fast. This makes it suitable for various applications in road construction and maintenance.

• Prime Coats: Applied to the base course to improve adhesion for subsequent asphalt layers. It penetrates the base material, binding loose particles and enhancing water resistance.
• Patching: Used as a binder for patching small potholes and cracks in asphalt pavements. It provides a temporary repair until permanent measures can be taken.
• Tack Coats: While less common with RC-250 due to its rapid curing, it can be used under certain conditions to provide adhesion between asphalt layers.
• Surface Treatments: In some cases, it can be used for surface treatments, but other types of bitumen might be more suitable depending on the specific requirements.

Advantage of Cutback Bitumen RC-250

Cutback bitumen RC-250 offers several advantages over other types of bitumen. These advantages include:

• Faster curing time: Cutback bitumen RC250 dries and sets quickly, allowing for faster construction times.
• Cost-effective: Cutback bitumen RC250 is a more affordable option compared to other types of bitumen, making it an ideal choice for large-scale construction projects.
• Versatility: Cutback bitumen RC250 can be used in various construction applications, including road construction, pavement, and maintenance.
• Excellent resistance to weathering and aging: Cutback bitumen RC-250 is known for its exceptional weathering and aging resistance, making it ideal for use in areas with extreme weather conditions.
• Easy to apply: Cutback bitumen RC-250 is easy to apply, making it ideal for use in remote locations where specialized equipment may not be available.

Safety Tips of Bitumen RC 250

Cutback Bitumen RC 250 is a hazardous material and should be handled with care. Some safety tips when using Bitumen RC 250 are:
