Cutback Bitumen RC 800
Description of Cutback Bitumen RC 800?
Cutback Bitumen RC 800 is a type of bituminous material meticulously Used in road construction. The “RC” stands for “Rapid Curing,” indicating its fast-curing properties, while the “800” signifies its viscosity. RC 800 is classified as a rapid-curing cutback bitumen, and its relatively low viscosity makes it ideal for specific applications requiring quick setting times. This process allows the bitumen to be applied easily for various construction purposes. The properties of cutback bitumen, such as viscosity and curing time, can be tailored by adjusting the type and amount of solvent used.
- RC: The “RC” in RC 800 stands for “Rapid Curing.” This indicates the curing properties of the cutback bitumen. Rapid-curing bitumens have a fast rate of solvent evaporation and curing, which means they solidify relatively quickly after application.
- 800: The number “800” represents the viscosity of the cutback bitumen. In this case, RC 800 has a relatively low viscosity, indicating that it is less viscous and flows more easily compared to cutback bitumens with higher viscosity numbers.
Cutback Rapid Curing 800 is dissolved bitumen in the solvents of kerosene. 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.
Application of Bitumen RC 800
Cutback bitumen RC 800 is widely used in road construction and maintenance. Some common applications of cutback bitumen RC 250 include:
- Prime Coat: RC 800 can be used as a bonding agent, promoting adhesion between the existing road surface and the new asphalt layer, and it helps to prevent moisture infiltration.
- Tack Coat: RC 800 can be used as a tack coat between the layers When constructing multiple layers of asphalt. It ensures a strong bond between the old and new asphalt layers, reducing the likelihood of delamination and improving the overall structural integrity of the road.
- Repair: RC 800 can be used In road maintenance and used for patching and repairing damaged or deteriorated sections of asphalt roads.
- Surface Treatment: RC 800 can be used in surface treatment applications. It is sprayed onto the road surface and then covered with a layer of aggregate or chips.
Properties of Cutback Bitumen Rapid Curing 800
- Viscosity: Cutback Bitumen RC 800 has a medium to high viscosity, which means it has a relatively thick consistency. The viscosity can vary depending on regional standards, but RC 800 is generally thicker than some other cutback bitumen types. This property allows it to adhere well to aggregates and provide stability to road surfaces.
- Solvent Type: RC 800 is typically prepared using a rapid-curing solvent. This solvent evaporates relatively quickly after application, which helps the bitumen harden and adhere rapidly to the road surface. The choice of solvent can affect the curing time and performance of the product.
- Temperature Sensitivity: Like all cutback bitumens, RC 800 is temperature-sensitive. Its viscosity decreases as the temperature rises, making it easier to work with and apply at ambient temperatures. However, in colder conditions, it may become too thick and require heating for proper application.
- Adhesion: Cutback Bitumen RC 800 exhibits good adhesion to aggregates and other road construction materials. This adhesion is crucial for creating a stable and durable road surface.
Safety Tips of Cutback Bitumen RC 800
Cutback Bitumen RC 800 is a hazardous material and should be handled with care. Some safety tips when using Bitumen RC 800 are:
- Protective Equipment: Always wear appropriate PPE when handling Cutback Bitumen RC 800, including gloves, safety goggles, and protective clothing.
- Ventilation: Ensure that there is adequate ventilation when using Bitumen RC 800, as the fumes can be hazardous.
- Handling and Transfer: Transport Cutback Bitumen RC 800 in approved containers and vehicles, following all safety regulations.
Packing of Bitumen RC 800
The Cutback Bitumen RC 250 is usually packed in bulk, Steel Drum, and IBC Tank but The packing type depends on the quantity of the product and the specific requirements of the customer.
- 1MT IBC Tank
- 200 Kg New Steel Drum- Palletized
- Bulk in Tuck Tanker
