Bitumen 75/30

Oxidized Bitumen 75/30 Overview

Oxidized Bitumen 75/30, also referred to as Blown Asphalt 75/30 or Blown Bitumen 75/30, is a high-quality product that undergoes an oxidation process. Unlike pure bitumen, typically classified as penetration grade bitumen 60/70, oxidized bitumen 75/30 has a higher softening point and lower penetration grade. This transformation happens when heated air blows over bitumen, causing asphaltenes to polymerize, resulting in a more flexible and durable material. It is often known as Rubberized Bitumen due to its rubber-like qualities. Oxidized Bitumen 75/30 offers excellent performance, particularly in demanding applications.

Production Process of Oxidized Bitumen 75/30

To create Oxidized Bitumen 75/30, manufacturers heat penetration grade bitumen to a temperature range of 220°C to 230°C. The refinery’s BBU reactor enables the interaction between heated air and the hydrogen atoms of bitumen, As a result, steam forms and evacuates from the oxidation chamber, leaving behind high-quality oxidized bitumen with superior characteristics. This process ensures the product has enhanced temperature stability and durability.

Advantages of Oxidized Bitumen 75/30

Oxidized Bitumen 75/30 provides a range of significant benefits, including:

– Complete resistance to water: The oxidation process creates a dense structure, making the bitumen highly resistant to moisture. This property is crucial for applications like road construction and waterproofing.
– Extraordinary pliability: The polymerization of asphaltenes during oxidation gives the bitumen exceptional flexibility, even in extreme temperatures.
– Durability: Oxidized Bitumen 75/30 offers long-lasting performance, even in harsh environmental conditions.
– Chemical stability: This bitumen resists chemicals and environmental stressors, maintaining its integrity over time.

Uses of Oxidized Bitumen 75/30

Due to its enhanced properties, Oxidized Bitumen 75/30 is suitable for a variety of applications, such as waterproofing, roof coatings, road construction, and asphalt manufacturing. Its high-temperature stability makes it ideal for regions with extreme heat, where traditional bitumen may not perform as well.
