Oxidized Bitumen

Quick Answer

Oxidized Bitumen, also known as Blown Bitumen or Air-Blown Bitumen, is a specially processed bitumen manufactured by blowing hot air through penetration-grade bitumen. This controlled oxidation process increases the material’s hardness, softening point, elasticity, and resistance to heat, aging, and weathering. Oxidized Bitumen is widely used for roof waterproofing, pipe coatings, industrial flooring, bridge construction, insulation systems, expansion joints, adhesives, and protective coatings.

As a trusted Oxidized Bitumen supplier in Pakistan, SHM TRADE GLOBAL supplies premium-quality Oxidized Bitumen for construction, waterproofing, industrial, and infrastructure projects, ensuring international quality standards, competitive pricing, and reliable nationwide delivery.

Key Takeaways

• Oxidized Bitumen is produced by blowing air through penetration-grade bitumen.
• It offers superior heat resistance, waterproofing, durability, and chemical stability.
• Common grades include Bitumen 85/25, Bitumen 95/25, and Bitumen 115/15.
• It is extensively used in roofing, waterproofing, pipe coatings, industrial flooring, and insulation systems.
• SHM TRADE GLOBAL supplies premium Oxidized Bitumen across Pakistan and international markets.

What Is Oxidized Bitumen?

Oxidized Bitumen is a thermoplastic hydrocarbon material produced by passing hot air through refined petroleum bitumen under controlled temperature conditions. During this oxidation process, the molecular structure of the bitumen changes, resulting in a harder, more durable product with a higher softening point and improved resistance to heat and aging.

Unlike conventional paving bitumen, Oxidized Bitumen is specifically engineered for industrial and waterproofing applications where long-term performance, dimensional stability, and resistance to environmental conditions are essential.

Because of its outstanding waterproofing capabilities and excellent adhesion to concrete, metal, and masonry surfaces, Oxidized Bitumen has become one of the most widely used materials for roofing systems, industrial coatings, pipe protection, and infrastructure waterproofing.

How Is Oxidized Bitumen Manufactured?

The production process begins with high-quality penetration-grade bitumen. Heated air is continuously injected into the molten bitumen under carefully controlled temperatures. This oxidation process modifies the physical properties of the binder by increasing its viscosity and softening point while reducing its penetration value.

The resulting product exhibits:

• Higher heat resistance
• Improved weather resistance
• Increased hardness
• Better elasticity
• Excellent waterproofing properties
• Enhanced durability
• Longer service life

These characteristics make Oxidized Bitumen ideal for demanding industrial and construction environments.
