Oxidized Bitumen 95/25 is a type of petroleum-based bitumen that has undergone a unique refining process to enhance its properties and make it more suitable for various applications. This refined bitumen is a blend of hydrocarbons that are derived from crude oil and have been oxidized to create a highly viscous and sticky material. The “95/25” in the name refers to the bitumen’s penetration and softening point, respectively, which are key indicators of its quality and performance.

In addition to its impressive durability, Oxidized Bitumen 95/25 also boasts a range of other desirable properties. It has a high viscosity, which gives it excellent adhesion and bonding capabilities, making it ideal for use in conjunction with aggregate materials such as sand, gravel, and stone. It also has a relatively low softening point, which allows it to remain flexible and resistant to cracking even in extreme temperatures. This makes it an excellent choice for applications where temperature fluctuations are a concern, such as in roofing and waterproofing.

Description of Oxidized Bitumen 95/25

Oxidized Bitumen 95/25 is industrial bitumen which is dark, petroleum residue modified by the oxidation process. Oxidized Bitumen is produced by passing air through bitumen under controlled temperature conditions. Its consistency ranges from highly viscous to solid. Blown bitumen grade has technical advantages such as durability, flexibility, water-resistant and chemical stability. Oxidized Bitumen 95/25 has a high softening point and, a high flash point and it is highly stable during melting.

Oxidized Bitumen 95/25 is produced by either a 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 oxidizes. The different grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges.

Oxidized Bitumen grades are blown or oxidized bitumen ‘s which are 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.

The different grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges. The softening point value measured by Ring and Ball method as determined by ASTM D36. Also, the penetration value is in 1/10 mm as determined by IP49 or ASTM- D5.

The Capability of Oxidized Bitumen 95/25

Applications

Oxidized asphalt 95/25 used in chemical, fuel, lacquers, varnishes, paint paper-pulp-board, textile
processing, road construction, pavement, civil works, roofing, construction industries; sealing and
insulating buildings, adhesive, crack seal and repairmen, construction materials additive, dust-binding,
insulating and impregnating agents, make rubber and plastic products.

The asphalt R 95/25 products are for paving. also used in asphalt-based paints for corrosion protection of metals, in lining public works structures, adhesives in electrical laminates, the base for synthetic turf; typical uses for oxidized
bitumen 95/25 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. Blown bitumen R 95/25 is using insulation and isolation bitumen membrane sheet.

Also, 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.
Notice: The oxidized bitumen should be heated at double temperature against the softening point to be
able to have flow and viscosity.

Handling and Storage

• 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.
• 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 Bitumen material should be broken up prior to placement in the boiler. 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 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.
• For Health and Safety information, please make reference to the relevant MSDS.
