Oxidized Bitumen 110/30, also referred to as Blown Bitumen 110/30, Blown Asphalt 110/30 or Oxidized Asphalt 110/30, is a high-softening-point grade designed for use in high-temperature, chemically aggressive, and static industrial applications. With a softening point of 110°C and penetration between 20–30 dmm, this grade exhibits extreme rigidity, minimal flow, and outstanding durability.
This post outlines its technical data, physical characteristics, and practical industrial applications, helping engineers and decision-makers select the right material for critical environments.
Oxidized Bitumen 110/30 is produced by blowing air through penetration-grade bitumen under controlled conditions. This process introduces oxygen, leading to molecular polymerization that increases the material’s viscosity, stiffness, and thermal resistance. The result is a rigid, solid material ideal for use in static conditions that require high thermal and chemical endurance.
Unlike paving-grade bitumen, this oxidized grade retains its shape even under high loads and does not flow at elevated temperatures, making it suitable for structural and waterproofing applications where temperature, load, and chemical exposure are a concern.
Blown Asphalt 110/30 is widely used in expansion joint systems in bridges, dams, and buildings. Its rigidity and thermal endurance prevent joint failure caused by heat or stress.
Oxidized Bitumen 110/30 protects pipelines in oil, gas, and water distribution networks. It forms a chemically resistant barrier that guards against soil chemicals and corrosion.
Oxidized Asphalt 110/30 is ideal for lining tanks storing acids or corrosive materials. It does not degrade when in prolonged contact with chemical vapors or liquids.
Used in flat roofs exposed to high thermal loads, Oxidized Bitumen 110/30 maintains form and resists UV damage, cracking, and flow even in desert climates.
In building foundations and basement walls, it acts as a water-impermeable layer, shielding against moisture ingress, especially where chemical exposure is likely.
Factories and refineries use it beneath floors and platforms as a rigid, heat-resistant base that remains stable under equipment load and high temperatures.
✅ Excellent rigidity with zero flow at high temperatures
✅ Resistant to acids, alkalis, and chemicals
✅ Ideal for static and load-bearing applications
✅ Safe handling with high flash point
✅ Long lifespan with low thermal aging
What is the main use of Oxidized Bitumen 110/30?
Blown Asphalt 110/30 mainly used in static applications such as expansion joints, tank linings, and pipe coatings, where high heat and chemical resistance are critical.
Is this grade suitable for road construction?
No. Oxidized Asphalt 110/30 is stiffness and low ductility make it unsuitable for dynamic surfaces like roads or driveways. It is designed for structural and protective industrial use.
Can Oxidized Asphalt 110/30 be dissolved in solvents?
Yes. With a solubility greater than 99%, Oxidized Bitumen 110/30 easily dissolves in industrial solvents like trichloroethylene, making it useful in coatings and adhesives.
How is Oxidized Bitumen 110/30 packaged?
Blown Asphalt 110/30 typically supplied in:
25 kg meltable plastic bags
180 kg steel drums
1 metric ton blocks for bulk industrial applications
Custom packaging is available upon request.
How does Blown Asphalt 110/30 handle UV exposure?
It resists UV degradation better than penetration-grade bitumen, making it ideal for exterior and aboveground applications with high sun exposure.
Oxidized Bitumen 110/30 is a specialty material built for resilience, durability, and protection. Whether you’re managing a chemical plant, waterproofing a dam, or coating a pipeline, this bitumen grade delivers where others fail.
Thanks to its extremely high softening point, rigid structure, and long-term chemical resistance, it ensures the safety and durability of your critical infrastructure. If your project involves heat, static loads, and chemical exposure, Bitumen 110/30 is your optimal choice for performance and longevity.
