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.

Production Process of Oxidized Bitumen

The production of blown asphalt involves the air blowing process, which alters the physical properties of the bitumen. Here’s a detailed look at the production process:

Step-by-Step Production Process

1. Selection of Base Bitumen:
   • The process begins with the selection of high-quality base bitumen, which serves as the raw material. The quality of the base bitumen significantly impacts the properties of the final product.
2. Heating the Bitumen:
   • The selected base bitumen is heated to a temperature between 240°C and 300°C. This ensures that the bitumen is in a fluid state, facilitating the oxidation process.
3. Air Blowing:
   • The heated bitumen is subjected to air blowing, where air is introduced into the bitumen through a series of nozzles. The air reacts with the bitumen, causing oxidation. This process increases the softening point and reduces the penetration of the bitumen.
4. Control of Process Parameters:
   • The oxidation process is carefully controlled by monitoring parameters such as temperature, air flow rate, and duration of air blowing. These parameters are adjusted to achieve the desired properties in the final product.
5. Cooling and Packaging:
   • After the air blowing process, the oxidized bitumen is cooled to a manageable temperature and then packaged for distribution. It can be stored in solid blocks, drums, or other suitable containers.

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.

Benefits of blown bitumen

Oxidized bitumen offers several benefits that make it a preferred choice in various industries. Here are some of its key advantages:

1. High Temperature Resistance:
   • Oxidized bitumen has a higher softening point compared to regular bitumen, making it suitable for applications exposed to high temperatures.
2. Durability:
   • The reduced penetration and increased hardness enhance the durability and longevity of the material.
3. Flexibility:
   • Despite its hardness, oxidized bitumen retains a degree of flexibility, allowing it to withstand thermal expansion and contraction.
4. Chemical Resistance:
   • Superior resistance to chemicals, acids, and alkalis ensures long-term performance in harsh environments.
5. Waterproofing Properties:
   • Excellent waterproofing properties make it ideal for applications requiring moisture protection.
6. Cost-Effectiveness:
   • Provides a cost-effective solution for various industrial applications, offering long-term savings due to its durability.
