Cutback Bitumen RC-30
DESCRIPTION OF CUTBACK BITUMEN RC-30
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-30 cutback asphalt. Our 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 RAHA OIL are petroleum grade bitumen manufactured from the fractional / vacuum distillation of crude oil blended with a solvent. Bitumen supplied by RAHA 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 RAHA OIL are blended from petroleum grade bitumen as stated herein.
CUTBACK BITUMEN RC-30
Cutback Bitumen RC-30 is dissolved of 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. he 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 becoming a negligible component of the seal coat a few months after application. RC-30 is Rapid curing (RC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of rapid volatility. Our 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 RC-30 containing minimum 50% Bitumen, is commonly used for Prime Coating. Cutback bitumen RC-30 is dissolved of 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 becoming 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.

USES 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. This kind of bitumen is suitable to be used 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. 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. Cutback agents are used to lowering 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 RC-30 consists of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction. The cutback asphalt RC-30 applying to waterproof of surfaces plug capillary voids, coat, and bond loose mineral particles.
APPLICATION OF CUTBACK RC-30
Cutback agents are used to lowering the viscosity of bitumen when it is applied as a primer to the surface of a road pavement aggregate base course or substrate. Current common uses are in penetrating prime coats and in producing patching or stockpile mixtures. Slow curing cutback bitumen is a type of bitumen that is diluted with a slow-evaporating solvent, making it suitable for various applications where a slower curing time is desired.
HERE ARE SOME COMMON APPLICATIONS OF SLOW CURING CUTBACK BITUMEN:
- Road Construction: Slow curing cutback bitumen is often used in road construction for surface treatments, prime coats, and tack coats. The slow-evaporating solvent allows for a longer curing time, ensuring better penetration and adhesion to the road surface.
- Prime Coating: It is applied as a prime coat to prepare the base surface before the application of asphalt layers. The slow-curing properties help in achieving better penetration into the existing road surface, enhancing the bond between layers.
- Tack Coat: Slow curing cutback bitumen serves as a tack coat, promoting adhesion between asphalt layers during pavement construction. The extended curing time allows for optimal bonding between layers.
- Surface Dressing: It can be used in surface dressing applications, providing a weather-resistant and durable surface for roads.
- Dust Control: In areas where dust control is necessary, slow curing cutback bitumen can be applied to gravel or dirt roads. The slow evaporation of the solvent allows for better penetration and binding of surface particles, reducing dust emissions.
- Patchwork and Repair: Slow curing cutback bitumen is suitable for patching and repairing damaged road sections. The longer curing time ensures effective sealing of repaired areas.
- Temporary Pavements: It can be used in the construction of temporary pavements for events or construction sites where a slower curing process is preferred.
- Parking Lots: Slow curing cutback bitumen is employed in the construction of parking lots, providing a stable and durable surface.
- Emulsion Production: Slow curing cutback bitumen can also be used in the production of bitumen emulsions, which are widely used in various road maintenance and construction applications.
It’s essential to follow industry standards and guidelines when using slow curing cutback bitumen to ensure proper application and performance. The choice of cutback bitumen grade may vary based on specific project requirements and environmental conditions. Manufacturers and suppliers typically provide technical specifications and recommendations for their products.
