Manufacturer of Oxidized Bitumen 90/15 DUBAI UAE

General Description of Oxidized Bitumen 90/15

Oxidized Bitumen 90/15 is also known as hard bitumen, blown bitumen, bitumen oxide and hard asphalt. It is produced by passing air through the penetration grades. This process causes bitumen to be more rubbery than its original formula. Oxidized Bitumen 90/15 and other grades are simply harder bitumen.

Hard bitumen under controlled temperature conditions is widely used as an anti-slip layer compound in the piling industry, for the manufacture of roofing felts, the roofing and waterproofing industries, for sound dampening felts, and under carriage sealant in the automotive industry, electric cable joint protection, joint filling compound, sealant compound, and many others. Also used in sealing saw cuts and joints where expected movements are minimum. It is also used in the manufacturing of bituminous marine mastic for oil & gas pipeline joints.

Oxidized Asphalt 90/15 is an Oxidized Bitumen produced by oxidizing selected petroleum asphalts without adding the catalyst. Blown Asphalt 90/15 has a high softening point and high flash point and it is highly stable during melting.
Oxidized Asphalt 90/15 is produced by the air-blowing of penetration-grade bitumen. This is done at high temperatures, resulting in a material of a much higher penetration index.

Oxidized Bitumen 90/15 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. The designation of the Oxidized Asphalt 90/15 refers to the midpoint of the softening point acceptance criteria.
Oxidized Asphalt is a solid or semi-black solid material and is gradually liquid when heated. Oxidized Bitumen grades are blown or oxidized Asphalt which is produced by passing air through soft bitumen under controlled temperature conditions. This process gives the bitumen more rubbery properties than penetration or hard-grade bitumen and a variety of uses in industrial applications.

Blown Asphalt 90/15 is produced by either the Continuous or Staggered Blowing Process. Heated Penetration Grade Bitumen under a controlled environment is blown with air which controls the Oil Content in the Bitumen while it oxidized. The different grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges.

As said before, Oxidized Bitumen 90/15 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. In addition, the numbers relate to the midpoint of the material’s softening point and penetration respectively. The softening point value was measured by the Ring and Ball method as determined by ASTM D36. Also, the penetration value is 1/10 mm as determined by IP49 or ASTM- D5.

Bitukim is one of the market leaders in the Production, Export, and brokerage of different grades of Oxidized Asphalt with excellent quality. Our sales team is committed who understanding your requirements due to many years of experience in supplying bitumen products.

the 90/15 specification means :

1. The first number represents the softening point in degrees Celsius (i.e., 90°C), which indicates the temperature at which the bitumen begins to soften and lose its solid state.
2. The second number signifies the penetration grade (i.e., 15), which measures the depth (in tenths of a millimeter) to which a standard needle can penetrate the bitumen under specified conditions.

Oxidized Bitumen 90/15 has a different name, Some of these alternative names include:

• Blown Asphalt 90/15
• Blown Bitumen 90/15
• Oxidizing Bitumen 90/15
• Oxidized Asphalt 90/15
• Air Blown Asphalt 90/15
• Air-Rectified Bitumen 90/15

Usage of Oxidized Asphalt 90/15

It’s used as raw material for bitumen coats, roofing, and insulation also in the Isolation bitumen membrane sheet. Also Oxidized asphalt 90-15 uses in chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, and textile processing. In road construction, pavement, crack seal and repairmen, civil works, roofing also construction.
In addition, it uses for sealing and insulating buildings, adhesive, construction materials additives, dust-binding, and coating. With a wide range of uses in insulating and impregnating agents, make rubber and plastic products.

The blown asphalt 90-15 products are for paving and roofing. Also used in asphalt-based paints for corrosion protection of metals, inlining public works structures, adhesives in electrical laminates, and base for synthetic turf. Typical uses for Oxidized Bitumen 90/15 also include roofing, pipe coating, Portland cement pavement, hydraulic applications, and paint manufacturing.

Application of Oxidized Asphalt 90/15

Oxidized Asphalt 90/15 is a dark industrial bitumen. Petroleum residue is modified by the oxidation process. In addition, Oxidized Bitumen is produced by passing air through bitumen under a controlled temperature state. Its stability ranges from highly viscous to solid. Blown bitumen grade has technical advantages such as durability, flexibility, water-resistant and chemical stability. There are also different grades of blown bitumen.
Oxidized bitumen 90/15 is used in chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement, crack seal and repairmen, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating and impregnating agent, make rubber and plastic products. The Oxidized asphalt 90/15 products are for paving. also used in asphalt-based paints for corrosion protection of metals, inlining public works structures, adhesives in electrical laminates, a base for synthetic turf; typical uses for oxidized bitumen 90/15 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. Oxidized bitumen 90/15 is using the insulation and isolation bitumen membrane sheet. Also, the Car undercoating Automobile industry is especially required for Blown Asphalt. Vehicle undercoating material is based on Bitumen. Bitumen provides excellent waterproof, dustproof, and noise proof for automobile undercoating.
Oxidized bitumen 90/15 should be heated at double temperature against the softening point to be able to have flow and viscosity. To use oxidized bitumen 90/15, surfaces must be dry, clean, and free of loose particles, formwork, curing products, irregularities, slurry, etc.

Recommendations for Handling / Storage

The heating of packaged bitumen is a critical phase in most of the final uses. Typically, the packaged material is heated and melted in boilers out on site.
However, control at the heating phase is very important in terms of health and safety as well as in maintaining the quality of the product.
The note must be taken of the maximum safe handling temperature of 230 C and this should not be abused. Bitumen is a poor conductor of heat, consequently, control of the heating phase is of paramount importance.

The Oxidized Asphalt material should be broken up before the boiler placement. This exposes a larger surface area to the heat and encourages a more even heating regime. Without the larger exposed surface area, aggressive heating at the base and sides of the boiler may well result in localized overheating, altering the characteristics of the BituKim modified bitumen and potentially causing thermal cracking of the bitumen, creating the release of low lash vapors. The flash point of the oxidized bitumen then becomes irrelevant; as these low flash vapors determine the fire risk.
Melted bitumen should not be left in the boiler and reheated from cold, as there is then a high potential for localized overheating around the heating area (lack of convection means poor heat transfer) and potential development of a pressurized pocket of low flash vapors.

Be aware of the placement of any temperature monitoring or control devices. As a result of the poor thermal conductivity of the bitumen, a thermometer in the bitumen some distance from the heat source could read significantly different (even hundreds of degrees) from the true temperature of the bitumen near the heat source.

Health & Safety

workers should comply with these tips:

• Ventilation: workers anywhere working should have appropriate Ventilation Because Oxidized Bitumen can release fumes when heated, which can be harmful if inhaled.
• Protective Equipment: workers should use heat-resistant gloves, safety shoes, long-sleeved shirts, long trousers, and safety goggles.
• Fire Safety: Workers work with high temperatures for this reason Keep bitumen away from open flames or sparks and have appropriate fire extinguishing equipment on hand.
