Oxidized Bitumen 90/15, also known as Blown Asphalt 90/15, Oxidized Asphalt 90/15 or Bitumen 90/15 is a semi-solid grade of bitumen known for its high softening point, low penetration, and excellent thermal resistance.
This grade is widely used in industries requiring materials that can withstand high mechanical stress, moisture exposure, and elevated temperatures without deformation.
In this post, we examine the technical features, data sheet, and practical industrial uses of Oxidized Bitumen 90/15 — one of the most durable and thermally stable grades available.
Oxidized Bitumen 90/15 is produced through a controlled air-blowing process, where air is passed through heated penetration-grade bitumen. This chemical modification alters the asphaltene-to-maltene ratio, increasing viscosity, hardness, and oxidation resistance.
The result is a hard yet workable asphalt that remains stable under high-pressure loads and intense heat, making it ideal for construction joints, pipe coatings, and industrial sealants.
Oxidized Bitumen 90/15 is used as a preformed filler in expansion joints for bridges, airport runways, dams, and industrial floors. It can tolerate large temperature swings and resist mechanical stress without cracking.
Blown Asphalt 90/15 is ideal for coating metal pipes, especially underground and offshore pipelines. It provides a watertight, corrosion-resistant shield that prevents rust and degradation caused by chemicals, moisture, and soil acidity.
Due to its thermal durability and dimensional stability, 90/15 is widely used in roofing felts, waterproof membranes, and bituminous shingles. It resists deformation under sunlight and provides long-lasting waterproofing.
Blown Bitumen 90/15 is used in cable-jointing compounds and insulation coatings where electrical insulation, resistance to moisture, and mechanical integrity are required.
Because of its low penetration and good adhesion properties, 90/15 is a base for industrial adhesives, cold-applied mastics, and hot-melt sealants used in both construction and mechanical systems.
In aggressive environments, 90/15 is used to protect concrete pillars, steel bars, foundations, and tanks. It acts as a barrier against saltwater, chemicals, and industrial pollutants.
✅ Heat-Resistant and Structurally Stable
✅ Strong Adhesion and Waterproofing
✅ Ideal for High-Stress, High-Load Applications
✅ Excellent Corrosion and Chemical Resistance
✅ Long-Term Durability and Cost Efficiency
The grade 90/15 refers to a softening point of ~90°C and a penetration rate of ~15 dmm, signifying a hard, heat-resistant material.
Yes. Oxidized Asphalt 90/15 used in roofing felt production, waterproof membranes, and torch-on roofing sheets due to its high heat resistance and low flow.
No. This grade is not flexible. For flexible applications, lower grades like 85/25 or 75/35 are more suitable due to their higher ductility.
Oxidized Bitumen 90/15 is typically packed in:
25 kg meltable polyethylene bags
180 kg new steel drums
1 metric ton blocks
Custom packaging on request
Blown Asphalt 90/15 is ideal for:
Expansion joints
Roofing membranes
Pipe coatings
Adhesives
Industrial insulation
Oxidized Bitumen 90/15 delivers superior thermal performance, water resistance, and structural rigidity in a wide range of industrial applications.
Whether you’re reinforcing concrete joints, protecting steel pipes, or manufacturing durable roofing materials, this grade provides exceptional stability under heat, pressure, and environmental exposure.
Its high softening point and low ductility make it a preferred material for static, high-stress environments. If your project demands long-lasting, maintenance-free performance, Bitumen 90/15 is the grade to trust.
