Best Quality of Oxidized Bitumen 75/25

General Description of Oxidized Bitumen 75/25

Oxidized Bitumen 75/25 is the semi-solid oxidized grade of pure petroleum bitumen categorized in polycyclic aromatic hydrocarbons. and Bitumen 75/25 is normal on petroleum bitumen which is made by blowing Bitumen 60/70 by hot air.

Blown Bitumen 75/25 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 75/25 specification means :

1. The first number represents the softening point in degrees Celsius (i.e., 75°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., 25), which measures the depth (in tenths of a millimeter) to which a standard needle can penetrate the bitumen under specified conditions.

Oxidized Bitumen 75/25 has a different name, Some of these alternative names include:

• Blown Asphalt 75/25
• Blown Bitumen 75/25
• Oxidizing Bitumen 75/25
• Oxidized Asphalt 75/25
• Air Blown Asphalt 75/25
• Air-Rectified Bitumen 75/25

Usage of Blown Asphalt 75/25

It’s used as raw material for bitumen coats, roofing, and insulation also in the Isolation bitumen membrane sheet. Also, Oxidized asphalt 75/25 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 75/25 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 75/25 also include roofing, pipe coating, Portland cement pavement, hydraulic applications, and paint manufacturing.

Applications oxidized bitumen 75/25

This kind of bitumen is suitable to be used in chemical, raw material for bitumen coat, lacquers, varnishes, paper-pulp-board, textile processing, pavement, crack seal and repairmen, civil works, bitumen coat for piping, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, road construction, dust-binding,

insulating and impregnating agent, isolation bitumen membrane sheet, make rubber and plastic products. typical uses for oxidized bitumen 75/25 include roofing, pipe coating, and hydraulic applications, R 75/25 is mainly used in paint manufacturing and coating in hot areas. The main hazards presented by Asphalt relate to the temperature of the material.

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 temperature for this reason Keep bitumen away from open flames or sparks and have appropriate fire extinguishing equipment on hand.

Surface Preparation

Before using Blown Asphalt, surfaces must be dry, clean, and free of loose types, curing products, disorders, and slurry. Furthermore, if you use this type of bitumen without cleaning the area bitumen 75/25 will easily remove.
