Description of Oxidized Bitumen (Blown Asphalt)

Oxidized bitumen, also known as blown asphalt, is produced by passing air through hot bitumen at elevated temperatures. This process alters the molecular structure of the bitumen, resulting in increased hardness, viscosity, and temperature resistance compared to conventional bitumen. Oxidized bitumen is commonly used in roofing, waterproofing, and paving applications due to its improved durability and weather resistance. It’s available in various grades and forms, ranging from soft to hard depending on the extent of the oxidation process.

The most popular grades are; grades 95/25, 85/25, 90/40, and 115/15. We are also capable of producing other grades of Oxidized bitumen upon request by our customers. Oxidized Bitumen high softening temperatures qualify them as the excellent sealant for prevention from bleeding in high-temperature applications. Blown Grade Bitumen shall be broken up into small pieces (for the blown grade in molded cake form) and heated slowly to the application temperature of 220ºC to 230ºC. Oxidized Bitumen is predominantly used in the piling industry as an anti-slip compound for the manufacture of undercarriage sealants in the automobile industry. It is also used as a sealant compound, as a joint filling compound apart from being used in the manufacture of roofing felts and sound dampening felts. Further, Oxidized Bitumen is used in the manufacture of bituminous marine mastic, which is required for the oil and gas pipeline joints. This Oxidized Bitumen is available in different grades like 95/25, 85/25, 75/25, 90/40 and 115/15. Oxidized is also capable of producing other grades of Oxidized Bitumen according to the specifications of individual clients.

Blown Asphalt Production Process

The production process of Blown Asphalt , or blown asphalt, involves the following steps:

  1. Heating: Bitumen, a viscous black material derived from crude oil through the refining process, is heated to elevated temperatures to reduce its viscosity and make it easier to handle.
  2. Air Blowing: Hot air is then blown through the heated bitumen using specialized equipment such as blowers or air distributors. This process introduces oxygen to the bitumen, initiating an oxidation reaction.
  3. Oxidation: The introduction of oxygen causes molecular rearrangement within the bitumen, resulting in the formation of oxygenated compounds and cross-linking of molecular chains. This process increases the hardness, viscosity, and temperature resistance of the bitumen.
  4. Cooling: Once the desired level of oxidation is achieved, the oxidized bitumen is allowed to cool gradually. The cooling process stabilizes the molecular structure and solidifies the bitumen into its final form.
  5. Packaging: The cooled oxidized bitumen is then packaged into various containers, such as drums or bags, for storage and transportation to end-users.

Throughout the production process, careful control of temperature, air flow, and oxidation time is essential to ensure the desired properties and quality of the final product. The degree of oxidation can be adjusted to produce oxidized bitumen with different hardness levels, viscosity grades, and softening points to meet specific application requirements.

What is Difference Between Penetration Bitumen and Oxidized Bitumen

The primary difference between penetration bitumen and oxidized bitumen lies in their properties and production processes:

  1. Penetration Bitumen:
    Penetration bitumen, also known as paving bitumen or asphalt, is derived from crude oil through the refining process.
    It is a viscoelastic material characterized by its penetration value, which indicates the depth to which a standard needle penetrates the bitumen sample under specific conditions.
    Penetration bitumen is commonly used in road construction for asphalt paving, where it provides flexibility, adhesion, and resistance to deformation under traffic loads.
    It typically has a lower softening point and viscosity compared to oxidized bitumen.
  2. Oxidized Bitumen:
    Oxidized bitumen, also known as blown asphalt, is produced by passing air through hot bitumen at elevated temperatures.
    The oxidation process alters the molecular structure of the bitumen, resulting in increased hardness, viscosity, and temperature resistance compared to penetration bitumen.
    Oxidized bitumen is commonly used in waterproofing, roofing, pipe coating, and other applications where enhanced durability and weather resistance are required.
    It typically has a higher softening point and viscosity compared to penetration bitumen.

In summary, while both penetration bitumen and oxidized bitumen are derived from crude oil and used in various construction applications, they differ in terms of their properties, production processes, and intended uses. Penetration bitumen is primarily used in road construction, while oxidized bitumen is favored for waterproofing, roofing, and other applications requiring enhanced durability and weather resistance.

Application of Bitumen Oxidized in Roofs (BUR)

Bitumen oxides, or bitumen antioxidants, are chemicals used in built-up roofing (BUR) systems primarily to extend the service life of the bitumen and to enhance the overall performance of the roofing system. Bitumen is the primary waterproofing material used in BUR systems.

The main roles of bitumen oxides in BUR roofing are:

  1. Oxidation Resistance: Bitumen Oxidized are added to bitumen to increase its resistance to oxidation, which is a chemical process where bitumen molecules react with oxygen from the air. This reaction can lead to brittleness, cracking, and loss of waterproofing properties in the bitumen. By incorporating antioxidants, the lifespan of the bitumen is extended.
  2. Stability: Bitumen oxidized contribute to the stability of the bitumen, ensuring that it maintains its physical properties over time. This stability is important for the overall performance of the roofing system, especially in resisting changes in temperature and exposure to sunlight.
  3. Environmental Resistance: Bitumen oxides help the bitumen withstand environmental factors, such as UV radiation from the sun, temperature fluctuations, and exposure to chemicals in the environment. This resistance helps prevent premature aging and degradation of the roofing system.
  4. Enhanced Performance: By improving the stability and resistance of the bitumen, bitumen oxides contribute to the overall performance of the BUR system. This includes better waterproofing, increased flexibility, and resistance to cracking and other forms of damage.

In summary, bitumen oxidized are used in BUR roofing to enhance the durability and longevity of the bitumen, which is the primary waterproofing material in these systems. By improving the resistance to oxidation and other environmental factors, bitumen oxides help extend the lifespan of the roofing system and improve its overall performance.
