Oxidized bitumen, commonly referred to as blown bitumen, is a specialized form of bitumen created by blowing air through penetration-grade bitumen at elevated temperatures. This controlled oxidation process modifies the physical properties of the base material, resulting in a product with a higher softening point and lower penetration value.
As a result, oxidized bitumen becomes more durable, weather-resistant, and suitable for a wide range of industrial applications.
Production Process of Oxidized Bitumen
The oxidation process is a critical stage that defines the quality of the final bitumen grade. During this process, hot air is passed through heated bitumen under controlled conditions to achieve the desired chemical transformation.
Chemical Reactions and Material Transformation
When air is blown into the bitumen, oxidation reactions occur, leading to the formation of asphaltenes and resins. These components improve the material’s hardness and elasticity, giving oxidized bitumen its unique performance characteristics.
Process Control Parameters
Key factors influencing the oxidation process include:
- Temperature range: typically between 230°C and 300°C
- Airflow rate: determines the degree of oxidation
- Processing time: affects penetration and softening point values
Careful control of these parameters produces standardized grades like Oxidized Bitumen 85/25, 90/40, and 115/15, each suited to specific industrial uses.
Applications of Oxidized Bitumen in Industry
Oxidized bitumen is widely used across industrial and construction sectors where enhanced stability and adhesion are essential.
Construction and Infrastructure Uses
- In construction, oxidized bitumen serves as a key component in:
- Roofing and waterproofing membranes
- Asphalt joint fillers

What licenses are required for bitumen for export?
In order to export bitumen in Iran, the exporter must obtain a bitumen export license from the Commodity Exchange Organization. To obtain this license, the exporter must submit the following documents:
- Business card
- Company registration certificate
- Bitumen standard certificate
- Bitumen purchase proforma invoice
- Bitumen sales contract
After the documents are reviewed by the Commodity Exchange Organization, if approved, a bitumen export license is issued.
In addition to the bitumen export license from the Commodity Exchange Organization, the exporter must also obtain other licenses. These licenses include:
- Customs clearance license
- Transport insurance
The customs clearance license is issued by Iranian Customs. To obtain this license, the exporter must issue a customs declaration.
Transport insurance is issued by an insurance company. The transport insurance policy protects bitumen against possible damage during transportation.
