General Description of Oxidized Bitumen 95/25
Oxidized Bitumen 95/25 is the semi-solid oxidized grade of pure petroleum bitumen categorized in polycyclic aromatic hydrocarbons. and Bitumen 95/25 is normal on petroleum bitumen which is made by blowing Bitumen 60/70 by hot air.
Oxidized Bitumen 95/25 is a type of bitumen that is made by blowing air through bitumen. The blowing process causes the bitumen to oxidize, which means that it reacts with oxygen. This reaction makes the bitumen harder, more resistant to water, and more adhesive.
This grade should be heated at double the temperature (200ᵒ-300ᵒC) against the softening point to be able to have flow and viscosity.
the 95/25 specification means :
- The first number represents the softening point in degrees Celsius (i.e., 95°C), which indicates the temperature at which the bitumen begins to soften and lose its solid state.
- The second number signifies the penetration grade (i.e., 25), which measures the depth (in tenths of a millimeter) to which a standard needle can penetrate the bitumen under specified conditions.
Oxidized Bitumen 95/25 has a different name, Some of these alternative names include:
- Blown Asphalt 95/25
- Blown Bitumen 95/25
- Oxidizing Bitumen 95/25
- Oxidized Asphalt 95/25
- Air Blown Asphalt 95/25
- Air-Rectified Bitumen 95/25
Uses of Oxidized Bitumen 95/25
It’s used as raw material for bitumen coats, roofing, and insulation also in the Isolation bitumen membrane sheet. Also Oxidized Bitumen 95/25 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 95/25 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 95/25 also include roofing, pipe coating, Portland cement pavement, hydraulic applications, and paint manufacturing.

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 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 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.
Health & Safety of Oxidized Bitumen 95/25
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.
