Oxidized Bitumen 90/10 – Full Specifications, Applications & Data Sheet
Discover the full specification and industrial uses of Oxidized Bitumen 90/10. Ideal for joint sealants, coatings, and roofing in hot climates.
🛢️ Oxidized Bitumen 90/10: Specifications, Properties & Industrial Applications
Oxidized Bitumen 90/10, also known as Blown Asphalt 90/10, Oxidized Asphalt 90/10 or Bitumen 90/10 is one of the hardest grades of bitumen produced through air-blowing of penetration-grade bitumen. With a high softening point (~90°C) and low penetration (~10 dmm), it is widely used in applications that demand high rigidity, excellent thermal resistance, and dimensional stability under pressure or extreme temperatures.
This blog explores the technical properties, specification standards, and key industrial applications of Bitumen 90/10 in construction, manufacturing, and insulation industries.
🔍 What is Oxidized Bitumen 90/10?
Oxidized Bitumen 90/10 is a hard, solid form of bitumen created by blowing air through hot bitumen to change its molecular structure. This process increases its asphaltene content, which enhances stiffness and reduces flow at high temperatures.
With a softening point near 90°C and a very low penetration rate, 90/10 bitumen is ideal for hot climates, rigid sealants, and load-bearing systems where flexibility is not required but structural integrity is crucial.
🏭 Industrial Applications of Oxidized Bitumen 90/10
🧱 1. Structural Joint Fillers in Concrete
Due to its hardness and high temperature resistance, Oxidized Bitumen 90/10 is used in preformed expansion joint fillers for bridges, buildings, dams, and concrete slabs. It acts as a compressible seal that resists deformation under heavy loads and high temperatures.
🛢️ 2. Anti-Corrosion Coatings and Linings
Bitumen 90/10 is a critical component in protective linings for:
Oil & gas pipelines
Steel storage tanks
Subterranean and offshore installations
Blown Asphalt 90/10 impermeability to water and resistance to chemicals makes it a durable anti-corrosive layer.
🏠 3. Roofing and Waterproofing Sheets
Oxidized Asphalt 90/10 is used in rigid roofing membranes and torch-applied waterproofing sheets where heat resistance and structural integrity are essential. It prevents flow at high rooftop temperatures while maintaining waterproof barriers.
🧪 4. Electrical Insulation Compounds
Thanks to its dielectric properties, 90/10 is used in cable-jointing compounds, electrical insulators, and sealing materials for electronics. It protects against moisture ingress and ensures long-term insulation.
🌡️ 5. Industrial Adhesives & Mastics
Blown Asphalt 90/10 is a base ingredient in solvent-based adhesives, cold-applied mastics, and pressure-sensitive compounds that require long-term hardness and resistance to deformation under heat and pressure.
🔥 6. High-Temperature Pipe Coatings
Used in bitumen-enamel pipe coatings, 90/10 provides strong adhesion, rigidity, and protection for steel pipes exposed to thermal cycling and mechanical loads.

❓ FAQs About Oxidized Bitumen 90/10
❓ What is Oxidized Bitumen 90/10 used for?
Oxidized Asphalt 90/10 used in rigid sealants, roofing, corrosion protection, and joint fillers, especially where high temperature resistance and hardness are required.
❓ What are the main properties of Bitumen 90/10?
Oxidized Asphalt 90/10 has a high softening point (~90°C), low penetration (~10 dmm), and very low ductility, making it extremely rigid, heat-resistant, and waterproof.
❓ Can Bitumen 90/10 be used in flexible applications?
No. Blown Asphalt 90/10 is not suitable for flexible or moving joints due to its very low ductility. Softer grades like 85/25 or 75/35 are better for flexibility.
❓ Is Blown Asphalt 90/10 suitable for hot or tropical climates?
Yes. With a high melting point and thermal durability, 90/10 is ideal for hot climates, direct sunlight exposure, and extreme surface temperatures.
❓ In what forms is Oxidized Bitumen 90/10 available?
Blown Asphalt 90/10 typically packed in:
25 kg meltable bags
180 kg steel drums
1 MT blocks
Custom packaging for export
🔍 Conclusion
Oxidized Bitumen 90/10 is a high-performance, hard bitumen designed for use in static, high-temperature industrial environments. With its exceptional softening point, rigidity, and durability, this bitumen grade excels in concrete joint fillers, anti-corrosive coatings, roofing systems, and dielectric insulation compounds.
Its stability against thermal deformation and its resistance to moisture and chemicals make it a go-to solution in demanding infrastructure and industrial applications. Whether you’re sealing structural joints or formulating heat-resistant adhesives, Bitumen 90/10 delivers long-term protection, rigidity, and reliability.
