Oxidized Bitumen 115/15 Characteristics, This grade of oxidized bitumen also known as Blown Asphalt, is a type of bitumen that has been treated by blowing air through it at elevated temperatures, which alters its physical and chemical properties.

Properties of Oxidized Bitumen 115/15

Softening Point
Softening Point: The softening point of Blown Bitumen 115/15 is typically around 115°C. This is the temperature at which the bitumen softens enough to allow a specific amount of penetration.

Penetration
Penetration: The penetration value of Oxidized Bitumen 115/15 is usually around 15 dmm (decimillimeters). This indicates its hardness; the lower the penetration value, the harder the bitumen.

Thermal Stability
High Thermal Stability: Due to the oxidation process, Blown Bitumen 115/15 has excellent resistance to temperature variations. It remains stable and does not flow easily at high temperatures, making it ideal for hot climates.

Water Resistance
Water Resistance: Oxidized Bitumen is highly resistant to water, making it suitable for waterproofing applications. It prevents water penetration and provides a protective barrier.

Oxidation Resistance
Oxidation Resistance: The oxidation process increases the bitumen’s resistance to further oxidation, which prolongs its lifespan and maintains its properties over time.

Flexibility
Flexibility: While harder than regular bitumen, Oxidized Bitumen 115/15 maintains a certain degree of flexibility, allowing it to accommodate minor movements without cracking.

Chemical Resistance
Chemical Resistance: Oxidized Bitumen 115/15 exhibits good resistance to chemicals, acids, and salts, making it suitable for use in harsh environments.

Adhesion Properties
Adhesion: It has strong adhesive properties, which makes it effective in binding materials together in various applications such as roofing, road construction, and industrial uses.

Durability
Durability: The product is known for its long-lasting performance, with resistance to aging and environmental factors, making it a reliable material for long-term applications.

Applications
Common Uses: Oxidized Bitumen 115/15 is widely used in roofing felt, waterproofing, pipe coating, electrical insulation, joint filler, and in the production of paints and varnishes.
These characteristics make Oxidized Bitumen 115/15 a versatile and durable material for various industrial and construction applications.
