Oxidized Bitumen

Unveiling the Manufacturing Process and Applications of Oxidized Bitumen

Oxidized Bitumen, often referred to as blown bitumen, has gained significant traction in various industries due to its exceptional properties and versatile applications. This specialized bitumen is manufactured through a unique oxidation process that enhances its viscosity, durability, and resistance to temperature fluctuations. In this comprehensive article, we delve into the manufacturing process of Oxidized Bitumen and explore its wide-ranging applications. With Peak Universal Business as a trusted supplier, we’ll guide you through the fascinating world of Oxidized Bitumen.

Understanding Oxidized Bitumen

Oxidized Bitumen is a bitumen product that undergoes a controlled air-blowing process to increase its softening point and improve its resistance to temperature changes, water, and aging. This specialized bitumen is characterized by its high viscosity, flexibility, and durability, making it ideal for various industrial applications.

Manufacturing Process of Oxidized Bitumen

The manufacturing process of Oxidized Bitumen involves the controlled oxidation of conventional bitumen under specific temperature and airflow conditions. Here’s a step-by-step breakdown of the process:

  1. Selection of Bitumen Grade

The process begins with the selection of a suitable grade of bitumen, typically sourced from petroleum refineries. The choice of bitumen grade depends on the desired properties and applications of the final product.

  1. Heating and Air Blowing

The selected bitumen grade is heated to a specific temperature range, typically between 240°C and 300°C, in a controlled environment. As the bitumen is heated, compressed air is blown through the molten bitumen to initiate the oxidation process.

  1. Controlled Oxidation

During the air blowing process, oxygen molecules react with the bitumen’s hydrocarbon chains, leading to the formation of oxygenated compounds and increasing the bitumen’s softening point. The oxidation process is carefully controlled to achieve the desired viscosity and performance characteristics.

  1. Cooling and Packaging

Once the oxidation process is complete, the Oxidized Bitumen is cooled to room temperature and then packaged in various forms, including flakes, powders, or solid blocks, depending on the intended applications.

Advantages of Oxidized Bitumen

  1. Enhanced Performance

Oxidized Bitumen offers enhanced performance compared to conventional bitumen, thanks to its increased softening point, improved flexibility, and better resistance to temperature fluctuations, water, and aging.

  1. Versatility

Due to its unique properties, Oxidized Bitumen finds applications in various industries, including road construction, waterproofing, and industrial coatings.

  1. Cost-Effectiveness

Despite its specialized manufacturing process, Oxidized Bitumen offers cost-effective solutions for long-term applications due to its durability and reduced maintenance requirements.

Applications of Oxidized Bitumen

  1. Road Construction

In road construction, Oxidized Bitumen is used as a binder in asphalt mixes to improve the pavement’s durability, resistance to rutting, and fatigue cracking. Its high softening point and excellent adhesion properties make it ideal for high-traffic areas and regions with extreme weather conditions.

  1. Waterproofing

Oxidized Bitumen is widely used in waterproofing applications to create a durable and flexible membrane that protects buildings, bridges, and other structures from water infiltration, corrosion, and decay. Its superior water resistance and longevity make it a preferred choice for both horizontal and vertical waterproofing systems.

  1. Industrial Coatings

In the manufacturing sector, Oxidized Bitumen is used as a key ingredient in industrial coatings, sealants, and adhesives to enhance their performance, flexibility, and resistance to chemicals, UV radiation, and temperature extremes.

  1. Roofing

Oxidized Bitumen is also utilized in roofing materials to create weather-resistant and long-lasting roofing membranes. Its excellent adhesion properties and resistance to UV radiation and thermal cycling make it an ideal choice for flat and low-slope roofing systems.
