Cutback Bitumen SC-3000
GENERAL INFORMATION OF CUTBACK BITUMEN SC-3000
Cutback bitumen SC-3000 or 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. The SC liquid asphalt may be obtained by fluxing an asphalt cement with a less volatile distillate such as gas oil. The SC-70 and SC-250 grade cutback asphalts are very similar to residual refinery products that are used as heavy fuel oils such as bunker C or Number six fuel oils. These SC cutback materials, whether straight run or fluxed with a relatively non-volatile material such as gas oil, are also known as “road oils”.
USES OF CUTBACK BITUMEN SC-3000
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 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 SC-3000 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction. The cutback asphalt SC-3000 applying to waterproofing of surfaces plug capillary voids, coat and bond loose mineral particles.
- Road Construction: Cutback Bitumen SC-3000 is widely used in road construction as a binder. It provides adhesion between aggregate particles and forms a durable and flexible pavement. The medium-curing properties make it suitable for various weather conditions.
- Surface Treatment: It is used for surface treatment applications, such as chip sealing or asphalt spraying. The medium-curing cutback bitumen helps in creating a uniform and durable surface layer that protects the road from environmental factors.
- Prime Coating: Cutback Bitumen SC-3000 is applied as a prime coat to prepare the surface for asphalt paving. The prime coating enhances the bond between the existing surface and the subsequent asphalt layers.
- Patch Repair: In road maintenance and repair projects, Cutback Bitumen SC-3000 can be used for patching damaged areas. It helps in quickly repairing potholes and other surface defects.
- Dust Control: The medium-curing cutback bitumen is sometimes used for dust control on unpaved roads. It helps in stabilizing the road surface and reducing dust emissions.
- Adhesive: Cutback Bitumen SC-3000 can act as an adhesive in various applications. It is used to bind layers of asphalt, aggregate, or other materials in construction projects.
It’s important to note that the choice of cutback bitumen depends on the specific requirements of the project, climate conditions, and the desired curing time. Cutback Bitumen SC-3000 provides a balance between curing time and application flexibility, making it suitable for a range of road construction and maintenance applications.
PACKING OF CUTBACK BITUMEN SC-3000
Packing of cutback bitumen SC-3000 is in the new thick steel drum on the pallet to prevent any leak inside of container also bulk in bitutainers and tanker. Cutback Bitumen SC-3000 (Medium-Curing) is typically packed in various containers to facilitate storage, transportation, and application. The packaging methods may vary depending on the supplier and specific requirements, but common packaging options include:
Drums: Cutback Bitumen SC-3000 is often packed in standard steel drums. These drums typically have a capacity of 180 kg to 200 kg. Drums are a convenient and widely used packaging option, allowing for easy handling and transportation.
Bulk Containers: For larger quantities, cutback bitumen can be transported in bulk containers or tankers. Bulk containers are suitable for large-scale construction projects where a significant volume of bitumen is required.
Intermediate Bulk Containers (IBCs): IBCs are large containers with a capacity ranging from 500 liters to 1,000 liters. They provide a more efficient means of transporting medium to large quantities of cutback bitumen.
Flexitanks: Flexitanks are flexible and collapsible containers designed for the transportation of non-hazardous liquids, including cutback bitumen. They are an alternative to traditional drums and are suitable for shipping large volumes.
Tank Trucks: In some cases, cutback bitumen SC-3000 may be delivered via tank trucks directly to the construction site. Tank trucks are equipped with specialized tanks designed for transporting liquid bitumen.
It’s essential for suppliers and users to adhere to safety regulations and guidelines when handling, storing, and transporting cutback bitumen. Proper packaging ensures the integrity of the product and minimizes the risk of spills or leaks during transportation. The choice of packaging depends on factors such as the volume of bitumen needed, the distance of transportation, and the specific requirements of the construction project.
SAFETY OF CUTBACK BITUMEN SC-3000
