Oxidized Bitumen 105/15

Oxidized Bitumen 105/15 is one of the most renowned bituminous materials. Many professionals also call the material as hard bitumen or blown asphalt. This material elevates the standards of durability and performance.

At its core, Oxidized Bitumen 105/15 is a modified form of bitumen, the lifeblood of many construction projects. What sets it apart is the intricate production process it undergoes, a process that transforms ordinary bitumen into a powerhouse of resilience. With a softening point reaching an impressive 105 degrees Celsius and a penetration value of 15 dmm, it boasts a unique set of technical advantages that make it a go-to choice for a wide array of applications.

oxidized bitumen applications

Many things make oxidized bitumen 105/15 special. For example, the oxidation process, where air is artfully introduced at elevated temperatures, is the secret sauce behind its robustness. This process not only toughens the bitumen but also imbues it with the ability to stand firm against the harshest weather conditions.

Production Process of Oxidized Bitumen 105/15

The process of oxidizing bitumen involves a carefully orchestrated series of steps. In this method, a flow of bitumen and a simultaneous flow of air or another oxidizing agent are directed into a pressurized reactor, specifically designed as a rotary apparatus. 

To boost the interaction between the oxidizing agent and bitumen within the reactor, we employ mixing devices of the rotor-stator type. These devices create turbulence and shear forces, ensuring a thorough dispersion of the oxidizing agent and optimizing the overall oxidation reaction.

Oxidized Bitumen should be pictured as bitumen that undergoes a significant transformation in its properties due to a reaction with air at high temperatures. For practical considerations, the preferred softening point (or ball and ring temperature) of oxidized bitumen ranges between 100°C and 110°C. Moreover, the best performance is achieved when the oxidized bitumen penetrates at 25°C falling between 10 to 20 mm.


Technical Advantages of Oxidized Bitumen 105/15

  1. Enhanced Durability: Oxidized Bitumen 105/15 is engineered to withstand the test of time. Its enhanced durability makes it an ideal choice for various applications, ensuring longevity and performance.


  2. Weather Resistance: Unpredictable weather conditions are no match for it. Whether facing scorching sun or heavy rain, this material maintains its integrity, providing reliable protection.


  3. Adhesion and Cohesion: Due to its modified composition, it exhibits superior adhesion and cohesion. This means it forms a strong bond with surfaces, ensuring stability and longevity in applications.


How to Apply Oxidized Bitumen 105/15

Applying Oxidized Bitumen 105/15 is a straightforward process. Whether you are working on roofing, waterproofing, or protective coatings, you should ensure a clean and dry surface. Using standard application tools, spread the bitumen evenly, taking care to achieve the desired thickness. 

How to Store and Handle 

Proper storage and handling are crucial to maintaining the quality of Oxidized Bitumen 105/15. It should be stored in a cool, dry place away from direct sunlight. Ensure the containers are tightly sealed to prevent contamination. When handling, use appropriate safety gear, including gloves and protective clothing, to avoid skin contact.
