Cutback Bitumen RC-800

 

Cutback Bitumen RC-800 Description

Cutback Bitumen RC-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.
When gasoline or naphtha is used to flux asphalt cement, the final product is called “rapid curing” (RC) cutback asphalt. Specifications permit up to 45 percent distillate in manufacturing an RC-800 cutback asphalt.

Our Cutback Bitumen RC-800 complies with cutback petroleum asphalts of the rapid-curing type for use in the construction and treatment of pavements as per ASTM D2028-97 reapproved in 2004. Cutback Grade Bitumen is normally used in spraying and in some mixing applications. Cutback Bitumen is penetration grade bitumen blended with a solvent such as kerosene, white spirit, gasoline, and naphtha, controlling the curing time. Cut back petroleum asphalts of the rapid curing type supplied by ZUMRUT Company are petroleum grade bitumen manufactured from the fractional / vacuum distillation of crude oil blended with a solvent. Bitumen supplied by ZUMRUT is produced from the vacuum residue (short residue) feedstock. Penetration Grade bitumen’s are specified by the penetration and softening point test. Designation is by penetration range only. The penetration grade bitumen’s have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability, and application temperatures of bitumen. The cutback bitumen (Asphalts) supplied by ZUMRUT are blended from petroleum grade bitumen as stated herein.

Cutback Bitumen RC-800 Applications

Cutback Bitumen RC-800 is typically used for specialized applications due to its high viscosity and slow curing properties. Some common applications include:

  • Waterproofing: RC-800 is used for waterproofing applications, such as sealing joints, cracks, and gaps in concrete structures like bridges, tunnels, and dams. Its high viscosity allows it to fill voids effectively, creating a durable waterproof barrier.
  • Roofing: It can be used as a waterproofing agent for roofing materials, providing protection against water penetration and extending the lifespan of roofs, particularly in areas with extreme weather conditions.
  • Pipe Coating: RC-800 is applied as a protective coating for pipelines, providing corrosion resistance and extending the service life of the pipes, especially in corrosive environments such as oil and gas fields.
  • Industrial Applications: It finds use in various industrial applications where a thick, durable coating is required to protect surfaces from chemical corrosion, abrasion, and environmental degradation.
  • Marine Applications: RC-800 is utilized in marine environments for protecting structures like docks, piers, and seawalls from saltwater corrosion and erosion.

Packing of Bitumen RC800

Packing of cutback bitumen RC800 is in new thick steel drum on the pallet to prevent any leak inside of the container, IBC Tank, and also bulk in bitutainer.

Guaranty and Safety of Bitumen RC-800

The guarantee and safety of Bitumen RC-800 depend on several factors:

  • Quality Assurance: Procuring Bitumen RC-800 from reputable suppliers who adhere to industry standards and regulations ensures product quality and consistency.
  • Compliance: Ensuring that the Bitumen RC-800 meets relevant specifications and standards set by regulatory authorities guarantees its suitability for intended applications.
  • Proper Handling: Following recommended handling procedures and safety precautions during storage, transportation, and application minimizes the risk of accidents and ensures worker safety.
  • Environmental Considerations: Adhering to environmental regulations and best practices for the disposal of Bitumen RC-800 and its by-products reduces environmental impact and promotes sustainability.
  • Performance Testing: Conducting performance tests, such as viscosity, penetration, and softening point tests, verifies the quality and suitability of Bitumen RC-800 for specific applications, providing assurance of its performance.
