General Information on Bitumen RC-30 (Cutback)
Bitumen RC-30, also known as cutback asphalt, is a type of asphalt cement containing a solvent or distillate such as gasoline, diesel fuel, kerosene, or naphtha. These additives help keep the bitumen liquid at ambient temperatures, making it highly effective in coating aggregates. This property also enhances its workability during road construction, particularly in various weather conditions.
Classification and Composition
Bitumen RC-30 follows a specific classification system, where the term “RC” stands for rapid curing. It typically contains between 12% and 40% distillates, although this percentage can be as high as 45% for RC-30. The product is widely used in applications requiring a fast-curing process, and its chemical composition helps optimize the performance of road construction projects.
Compliance and Applications
Gold Bitumen Co.’s RC-30 complies with ASTM D2028-97 for rapid-curing petroleum asphalts. This high-performance product is ideal for use in pavement construction, surface treatments, and various mixing applications. Cutback bitumen is created by blending penetration-grade bitumen with solvents like kerosene, white spirit, or naphtha, which efficiently control curing times and improve adaptability to different climates.
Production and Properties
Manufactured using vacuum distillation from crude oil, Gold Bitumen’s Bitumen RC-30 ensures superior quality. The product undergoes rigorous testing for penetration and softening points. The thermoplastic nature of bitumen RC-30 means it softens at higher temperatures and hardens when cooled, making it ideal for various construction needs. This temperature-viscosity relationship is critical in determining adhesion, durability, and overall performance in diverse conditions.
Key Applications of Bitumen RC-30
RC-30 is widely used in road construction and surface treatments due to its lower viscosity, making it perfect for priming road aggregates and bonding asphalt layers. Some of its main applications include:
- Prime Coat & Cold Application: Bitumen RC-30 can be applied without thinning or heating, which reduces time and energy costs.
- Surface Penetration: It enhances the incorporation of asphalt into non-asphalt-based courses, improving the road surface’s durability.
- Waterproofing: This bitumen serves as an effective sealant, preventing water infiltration and ensuring longevity of pavements.
