Cutback asphalt 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. C 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 jey pasargad are blended from petroleum grade bitumen as stated herein.
Cutback agents are used to lower the viscosity of bitumen when it is applied as a primer to the surface of a road pavement aggregate base course or substrate. Kerosene is used as a bitumen cutback agent at different concentrations according to local conditions and requirements.
The cutback bitumen is ideal for prime coat and cold applied because of easy uses and no need to thinning and heating.
Cutback bitumen RC800 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.
The cutback asphalt RC800 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles.
Packing of cutback bitumen RC800 is in new thick steel drum on pallet to prevent any leak inside of container also bulk in bitutainer and tanker.
jey pasargad guaranty the quality of cutback RC800 with arrangement of international inspector to check quality and quantity of the bitumen on each shipment during the loading to vessel and controlling the production by QC team via batch test report before shipping. jey pasargad guaranty the quality to meet with ASTM/EN 15322:2009
