What is Oxidized Bitumen 90/15? Applications and Production Process

Oxidized bitumen 90/15, commonly known as blown asphalt, is a specialized bitumen variety developed through a detailed air-blowing process. This process involves introducing air into bitumen at high temperatures, fundamentally transforming its properties to enhance performance. 

The result is a product that uniquely balances hardness and flexibility, making it an ideal material for various construction applications. The special characteristics of the material offer increased durability and resilience, particularly beneficial in environments with fluctuating temperatures and conditions.

Applications of Oxidized Bitumen 90/15

The industry leaders prefer to use blown asphalt 90/15 for its durability and waterproofing properties. These properties are perfect for the industries listed below:

Road Construction: You can choose the material as your key element is in paving highways and airport runways. Because it can withstand heavy traffic and harsh weather. The enhanced strength and resilience of oxidized bitumen 90/15 help in maintaining road integrity over extended periods, reducing the need for frequent repairs.

Waterproofing: you can use it in roofing, basement sealing, and water tank protection. Its effectiveness in preventing water penetration makes it ideal for commercial buildings and residential structures. In addition, it ensures long-lasting protection against moisture and leaks.

Industrial Applications: Additionally, you can utilize 90/15 in the manufacturing of insulation and soundproofing products. Its application in industrial settings includes insulating machinery, creating soundproof panels, and providing thermal and noise insulation benefits.

Production Process of Oxidized Bitumen 90/15

Making hard bitumen 90/15 is quite a feat. It starts with heating standard bitumen to a piping-hot temperature. Then, air is blown through, triggering a chemical reaction that revamps its physical properties. The outcome? A 90/15 variant that is stronger, less penetrable, and has a higher melting point, ready to take on challenging construction and industrial tasks. This meticulous process guarantees consistent quality and performance in the final product.


Technical Advantages of Oxidized Bitumen 90/15

Oxidized bitumen 90/15 offers several technical advantages, making it a preferred choice in construction and industrial applications.

  • Its hardness and lower penetration rate compared to regular bitumen mean it is tougher and more deformation-resistant. So, it is perfect for fluctuating temperatures and heavy burdens.
  • The increased melting point ensures it stays stable even in hotter climates.
  • Its top-notch water resistance extends its use in waterproofing, effectively shielding structures from moisture damage.


How to Apply Oxidized Bitumen 90/15

Applying oxidized bitumen 90/15 requires careful preparation and execution to maximize its benefits.

Firstly, you should clean the surface where you will apply. In addition, you will ensure proper adhesion with dry, and free of debris. Please remember that preheating the bitumen to the recommended temperature is crucial for a smooth application.

During application, it is important to spread the material evenly, ensuring consistent coverage. For road construction, it is typically applied using specialized equipment that ensures an even distribution over the surface. In waterproofing, it is applied in layers, with each layer allowed to set before applying the next.

How to Store and Handle

Storing and handling Oxidized Bitumen 90/15, or blown asphalt, needs your careful attention. You should keep it in a cool, dry spot away from sunlight. And remember, when handling, to avoid any injuries, you must wear protective gear.
