Use of Oxidized Bitumen

Oxidized Bitumen, also known as blown bitumen, is a specially treated form of bitumen that undergoes an oxidation process to improve its properties. The process involves blowing hot air through the bitumen, which increases its viscosity and oxidation level. This results in a bitumen product with enhanced characteristics suitable for various applications. Let’s explore the uses and benefits of Oxidized Bitumen.


  1. Roofing and Waterproofing:
    Oxidized Bitumen is commonly used in roofing and waterproofing applications. It is applied as a roofing membrane or coating to provide a protective barrier against water penetration. The increased viscosity of oxidized bitumen helps it adhere to different surfaces, making it ideal for flat roofs, foundations, and basements. It offers excellent weather resistance, durability, and flexibility, ensuring long-lasting protection for buildings and structures.


  1. Joint Filling and Crack Sealing:
    Oxidized Bitumen is utilized for joint filling and crack sealing purposes. The high viscosity and adhesive properties of oxidized bitumen make it suitable for filling gaps and sealing cracks in asphalt pavements, concrete surfaces, and bridge decks. It forms a flexible and watertight seal that prevents further deterioration caused by moisture penetration, expanding and contracting with temperature changes.


  1. Pavement Preservation:
    Oxidized Bitumen is also used in pavement preservation techniques. It can be applied as a surface treatment, such as a seal coat or rejuvenating agent, to extend the life of asphalt pavements. The oxidized bitumen helps to restore the flexibility and durability of aging pavements, protecting them from oxidation, weathering, and fatigue cracking. It improves the skid resistance and waterproofing properties of the pavement, reducing maintenance needs and enhancing safety.


  1. Sound Dampening and Anti-Vibration:
    Due to its increased viscosity, Oxidized Bitumen is used for sound dampening and anti-vibration applications. It is commonly used as a material for sound barriers, road noise reduction, and vibration isolation pads. The thick consistency of oxidized bitumen helps absorb sound waves and vibrations, reducing noise pollution and enhancing comfort in various environments, such as highways, railways, and industrial settings.



  1. Electrical Insulation:
    Oxidized Bitumen is utilized as an electrical insulation material. Its high dielectric strength and resistance to heat make it suitable for applications in the electrical industry. It is used as an insulating material for power cables, joints, and terminations. The oxidized bitumen provides protection against electrical conductivity, moisture, and environmental factors, ensuring the safety and reliability of electrical systems.


In summary, Oxidized Bitumen is a versatile product with various applications in roofing, waterproofing, joint filling, crack sealing, pavement preservation, sound dampening, and electrical insulation. Its enhanced viscosity and improved properties make it a reliable choice for projects that require durable and long-lasting solutions. Whether it’s protecting structures from water damage, reducing noise levels, or insulating electrical systems, Oxidized Bitumen plays a vital role in different industries.
