Intro

Oxidized Bitumen 90/10 is a specialized form of bitumen that has undergone an oxidation process to enhance its properties and performance characteristics. This high-quality material is widely used in the construction and roofing industries due to its excellent weather resistance, durability, and adhesive properties.

What is Oxidized Bitumen 90/10?

Oxidized Bitumen 90/10 or Blown Bitumen 90/10 is a solid grade of pure petroleum bitumen manufactured by air-blowing through an asphalt flux. Special physical properties of its grade can be used in different applications in the construction business. It is a petroleum-based bitumen which is made by Oxidized Bitumen 60/70 by very hot air.
The numbers relate to the midpoint of the material’s softening point and penetration respectively.

The softening point value is the degrees Centigrade measured by the Ring and Ball method as determined by ASTM D36. The penetration value is in 1/10 mm as determined by IP49 or ASTM- D5. This product, utilized in the industrial sector, exhibits predominantly “solid” characteristics at ambient temperatures and provides SUPERIOR adhesive and waterproofing qualities when applied hot and allowed to cool than Oxidized Bitumen.

Process Manufacturing of Oxidized Bitumen 90/10

The manufacturing process of oxidized bitumen 90/10, often called blown bitumen, involves a series of carefully controlled steps designed to enhance the material’s properties for various industrial applications. This process begins with the selection of high-quality base bitumen, typically derived from the distillation of crude oil. The chosen base bitumen must meet specific standards to ensure it has the appropriate characteristics for oxidation.

1. Heating the Base Bitumen:

The first step involves heating the selected base bitumen to a temperature range of 240 to 300 degrees Celsius. This heating is essential to bring the bitumen to a molten state, ensuring it is sufficiently fluid for the subsequent oxidation process. The heating is typically carried out in specialized furnaces or heating tanks equipped with temperature control mechanisms to maintain the desired temperature range consistently.

2. Oxidation:

Once the bitumen reaches the required temperature, it is transferred to an oxidation chamber or reactor. The oxidation chamber is designed to introduce air into the molten bitumen in a controlled manner. Air is blown through the bitumen using a series of nozzles or spargers, initiating a chemical reaction between the oxygen in the air and the hydrocarbons in the bitumen. This process, known as air blowing, breaks down the molecular structure of the bitumen and forms new, more complex molecular chains. As a result, the bitumen’s viscosity increases, and its softening point is raised.

3. Controlled Conditions:

The oxidation process conditions, including temperature, airflow rate, and duration, are meticulously controlled to achieve the desired properties of oxidized bitumen 90/10. For this specific grade, the goal is to obtain a softening point of approximately 90 degrees Celsius and a penetration value of 10 dmm (decimillimeters). The precise control of these parameters ensures the final product meets the required performance standards. The duration of the oxidation process can vary but typically lasts several hours, depending on the desired final properties.

4. Cooling and Solidification:

After the oxidation process, the oxidized bitumen is gradually cooled to allow it to solidify. This cooling process is crucial to ensure the bitumen attains the desired hardness and consistency. Cooling can be done in air-cooled or water-cooled systems, depending on the production setup. The solidified bitumen is then removed from the cooling system and transferred to storage or further processing facilities.

5. Quality Control:

The solidified oxidized bitumen undergoes rigorous quality control testing to ensure it meets the specified parameters. Tests typically include measuring the softening point, penetration, and other relevant properties to confirm compliance with industry standards. Quality control ensures that the bitumen performs reliably in its intended applications, such as waterproofing, roofing, and industrial coatings.

6. Packaging and Distribution:

Finally, the oxidized bitumen 90/10 is packaged for distribution. The packaging can vary depending on customer requirements and intended use, including drums, bags, or bulk containers. Proper packaging is essential to protect the bitumen from contamination and facilitate easy transportation. The packaged bitumen is then distributed to various industries, where it is used in a wide range of applications, thanks to its enhanced durability and performance characteristics.
