Description of Cutback Bitumen RC-30
Cutback bitumen RC-30 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-30 cutback asphalt.
Cutback Bitumen RC-30 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 HJ OIL Co. are petroleum grade bitumen manufactured from the fractional / vacuum distillation of crude oil blended with a solvent. Bitumen supplied by HJ OIL Co. is produced from the vacuum residue (short residue) feedstock. Penetration Grade bitumens are specified by the penetration and softening point test. Designation is by penetration range only. The penetration grade bitumens 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 Huei Jie are blended from petroleum grade bitumen as stated herein.
Application of Cutback bitumen RC-30
Current common uses are in penetrating prime coats and in producing patching or stockpile mixtures. Cutback asphalt used in mixing with aggregate will usually contain an adhesion agent to assist in the coating of the aggregate surface.
Guaranty and Safety of Cutback bitumen RC-30
HJ OIL Co. guaranty quality of cutback Bitumen RC-30 with the arrangement of the international inspector. By checking the quality and quantity of the bitumen on each shipment during the loading to the vessel. Also controlling the production by QC team via batch test report before shipping.
Packing of Cutback bitumen RC-30
Packing of cutback bitumen RC-30 is in new thick steel drum on the pallet to prevent any leak inside of the container, IBC Tank, and also bulk in bitutainer.
