Oxidized bitumen 90/10

Oxidized Bitumen 90/10 & Its Importance in the Construction Industry

Oxidized bitumen, also known as blown bitumen, is a form of bitumen that has been treated by blowing air through it at high temperatures. This process modifies its physical properties, resulting in a product that is more rigid and less susceptible to temperature fluctuations. Among various grades, Oxidized Bitumen 90/10 stands out due to its specific balance of hardness and flexibility, making it highly valuable for certain construction applications.

Characteristics of Oxidized Bitumen 90/10

Oxidized Bitumen 90/10 is characterized by its penetration grade and softening point. The “90/10” specification indicates a softening point of approximately 90°C and a penetration range that is optimal for construction applications requiring a sturdy yet slightly flexible bitumen.

Key Characteristics:

  1. High Softening Point: Oxidized Bitumen 90/10 has a high softening point, which means it can withstand higher temperatures without becoming too soft.
  2. Low Penetration: This property indicates the bitumen’s hardness and resistance to deformation under load.
  3. Enhanced Adhesion: It adheres well to various substrates, making it ideal for coatings and waterproofing.
  4. Oxidation Stability: Due to the oxidation process, this bitumen is more stable and less reactive to environmental conditions.
  5. Temperature Resistance: It performs well in a wide range of temperatures, maintaining its integrity in both hot and cold environments.

Production Process of Oxidized Bitumen 90/10

The production of Oxidized Bitumen 90/10 involves the following steps:

  1. Selection of Base Bitumen: High-quality penetration grade bitumen is selected as the base material.
  2. Heating: The base bitumen is heated to a temperature between 240°C and 300°C.
  3. Air Blowing: Air is blown through the heated bitumen using a specially designed reactor. This process increases the bitumen’s viscosity and modifies its physical properties.
  4. Cooling and Packaging: The oxidized bitumen is cooled and then packaged in drums or other containers suitable for storage and transportation.

Uses of Oxidized Bitumen 90/10

Oxidized Bitumen 90/10 has a variety of uses in the construction industry due to its unique properties:

  1. Waterproofing: It is widely used for waterproofing roofs, basements, and foundations due to its excellent adhesion and impermeability.
  2. Pavement Construction: The high softening point and low penetration make it ideal for road construction in hot climates, where traditional bitumen might soften and deform.
  3. Sealants: It is used as a sealant for joints and cracks in concrete and asphalt pavements.
  4. Coatings: Oxidized Bitumen 90/10 is used as a protective coating for metals and concrete structures, providing resistance to water and chemical damage.
  5. Asphalt Mixes: It is used in the preparation of various asphalt mixes, enhancing their durability and performance under load.
