Oxidized Asphalt 105/15 Description:
Oxidized Asphalt 105/15, also known as Blown Asphalt 105/15 or Oxidized Bitumen 105/15, is a semi-solid grade of pure petroleum bitumen produced by air-blowing through an asphalt flux. This specific grade of oxidized asphalt exhibits unique physical properties that make it suitable for various applications in the construction industry.
Production Process: Oxidized Asphalt 105/15 is derived from petroleum bitumen, specifically Bitumen 60/70, through a process that involves blowing the bitumen with very hot air. The numerical values 105 and 15 correspond to the midpoint of the material’s softening point and penetration, respectively. The softening point is measured in degrees Celsius using the Ring and Ball method as per ASTM D36, while the penetration value is in 1/10 mm, determined according to IP49 or ASTM-D5 standards.
Quality Assurance: BITUPLUS Company ensures the quality of BITUPLUS Oxidized Asphalt 105/15 through rigorous inspection by international inspectors, verifying both quality and quantity during the loading process onto vessels. Additionally, production is monitored by quality control (QC) through batch test reports before shipping, guaranteeing compliance with ASTM standards.
Applications: Oxidized Asphalt 105/15 has diverse applications, including:
- Chemical industry for the production of fuel, paints, lacquers, varnishes, and more.
- Paper-pulp-board manufacturing and textile processing.
- Road construction and pavement applications.
- Paint manufacturing and crack sealing.
- Civil engineering projects.
- Roofing and construction industries for sealing and insulating buildings.
- Use as an adhesive and additive in construction materials.
- Dust-binding and coating applications.
- Insulation and impregnating agent.
- Manufacturing of rubber and plastic products.
- Paving applications.
- Asphalt-based paints for corrosion protection.
- Lining public works structures.
- Adhesives in electrical laminates.
- Base material for synthetic turf.
- Water-proofing applications and corrosion resistance for pipe coatings.
- Use in Portland cement pavement.
- Hydraulic applications.
- Caulking, mastics, and damp-proofing.
- Insulation and isolation bitumen membrane sheets.
- Vehicle undercoating in the automobile industry, providing waterproofing, dustproofing, and noise-proofing.
Application Guidelines: To use Oxidized Asphalt 105/15, surfaces must be dry, clean, and free from loose particles, formwork, curing products, irregularities, slurry, and similar contaminants. The bitumen should be heated to a temperature double that of its softening point to achieve the desired flow and viscosity.
Storage and Handling: Oxidized Asphalt 105/15 has a shelf life of up to 10 years and can undergo multiple heating and cooling cycles. It is advisable to store Oxidized Asphalt 105/15 in a sheltered area, protecting it from rain and direct sunlight.
Packing: BITUPLUS CO offers Oxidized Asphalt 105/15 in various packaging options, including Kraft bags, meltable plastic bags, drums, and bulk quantities. The product conforms to ASTM standards and is identified by two numbers indicating the softening point and penetration ranges, with 105/15 representing a softening point of 105°C and a penetration of 15 desi millimeters.
