What is Oxidized Bitumen 85/25?

Oxidized bitumen 85/25, also known as blown asphalt, stands as a versatile material in the road construction industry and general construction projects. Specially crafted to withstand diverse environmental conditions, it is renowned for its durability and resilience.

Production Process of Oxidized Bitumen 85/25

The production of oxidized bitumen 85/25 involves a meticulous process of controlled oxidation, enhancing the bitumen’s physical and chemical properties. During this process, air is blown through the bitumen to achieve the desired level of hardness and other essential characteristics. The odor of the material is just like that of other bituminous products.

This bitumen type is in semi-solid form. It contains around 90% carbon and 7% hydrogen. Other chemicals, such as nitrogen, sulfur, and metals, make up about 3%. The material has a lower softening point and a higher penetration level when compared to other types. The softening point of the material is 85 degrees Celsius, while the penetration level is 25 desi millimeters.

Technical Advantages of Oxidized Bitumen 85/25

• Enhanced Durability: Oxidized Bitumen 85/25 exhibits exceptional durability, making it an ideal choice for projects with stringent performance requirements.
• Weather Resistance: This unique bitumen variant is formulated to withstand the adverse effects of weather, ensuring longevity in various climates.
• Temperature Stability: Its inherent stability under different temperature conditions makes it suitable for a wide range of applications.

How to Apply Oxidized Bitumen 85/25

You can use this bitumen type for:

• Waterproof roofing
• Coating
• Road construction
• Varnishing
• Insulation purposes

Applying this bitumen type requires precision and adherence to industry best practices. Whether for road construction or general building projects, you should follow the steps below:

• Surface preparation: You should ensure the application surface is clean, dry, and free from any contaminants.
• Heating: You should heat the material to the recommended temperature for optimal fluidity.
• Application Technique: You should use appropriate tools and techniques to evenly apply the bitumen, taking care to achieve a consistent thickness.

How to Store and Handle

Proper storage and handling are crucial to maintaining the integrity of oxidized bitumen 85/25. The material can be kept in polybags or carton boxes. It is not important if you keep it with or without pallets. But you should follow these guidelines:

• Storage Conditions: You should store the material in a cool, dry place, away from direct sunlight and heat sources.
• Container Selection: You should choose suitable containers that prevent contamination and maintain the quality of the bitumen.
• Handling Precautions: When handling oxidized bitumen 85/25, you should use protective gear, such as gloves and safety goggles, to ensure safety and prevent skin contact.
• The black-brown material is hot in normal usage. Therefore, you should be careful while applying the product.

In conclusion, oxidized bitumen 85/25 stands as a cornerstone in construction, offering unparalleled durability and adaptability. By understanding its production, advantages, and proper application and storage techniques, you pave the way for successful and enduring construction projects.
