How Oxidized Bitumen is Produced? Its Uses, Applications, Benefits & Price Factors

How Oxidized Bitumen is Produced? Oxidized bitumen, also known as blown asphalt, Blown Bitumen or oxidized asphalt, is a versatile and essential material widely used in various industrial applications. Its unique properties make it a preferred choice in construction, waterproofing, and other sectors. This blog delves into the detailed aspects of oxidized bitumen, including its production process, uses, applications, benefits, how oxidized bitumen used? and price factors, with Peak Universal Business as a leading supplier.

What is Oxidized Bitumen?

Blown Asphalt is a type of bitumen that has undergone an oxidation process to enhance its properties, such as increased softening point and reduced penetration. This makes it more suitable for applications requiring high temperature resistance and durability. It is commonly referred to as blown asphalt due to the air blowing process used in its production.

Key Characteristics:

• Increased Softening Point: Higher resistance to deformation under high temperatures.
• Reduced Penetration: Enhanced hardness and durability.
• Elasticity: Improved flexibility, making it ideal for various applications.
• Chemical Resistance: Superior resistance to chemicals, acids, and alkalis.

The Air-Blowing Process Explained in Oxidized Bitumen Produced?

The air-blowing process is a thermal-oxidative method where hot air is injected into bitumen under controlled conditions.

🧪 Step-by-Step Production Process

1. Selection of Base Material
   High-quality penetration-grade bitumen (typically 60/70 or 80/100) is used.

2. Heating Phase
   Bitumen is heated to 230–270°C in a blowing reactor with agitation to ensure uniform heat distribution.

3. Air Injection (Oxidation)
   Dry air is blown through the molten bitumen. This process introduces oxygen, which reacts with hydrocarbons, resulting in polymerization and oxidation.

4. Controlled Monitoring
   Parameters like air flow rate, temperature, and blowing time (often 2–4 hours) are monitored to reach desired specifications.

5. Cooling and Packaging
   The finished product is cooled and packaged in bags, drums, or bulk blocks, depending on the application.

Quality Control

Quality control is a crucial aspect of the production process. Samples of the oxidized bitumen are tested at various stages to ensure that the final product meets the required specifications. Tests include:

• Penetration Test: Measures the hardness of the bitumen.
• Softening Point Test: Determines the temperature at which the bitumen softens.
• Ductility Test: Assesses the flexibility of the bitumen.
• Solubility Test: Ensures the bitumen is soluble in specific solvents.
