Oxidized Bitumen 75-35

History of Oxidized Bitumen 75-35

The history of oxidized bitumen can be traced back to the early 20th century when the first attempts were made to modify bitumen for use in road construction. The process of oxidizing bitumen by exposing it to air and heat was first discovered by accident in the late 1800s when a tank of bitumen caught fire and burned for several days. After the fire was extinguished, it was observed that the bitumen had become harder and more viscous, leading to the discovery of the oxidation process.

The first commercial production of oxidized bitumen began in the United States in the 1920s, and the process quickly gained popularity due to the improved durability and resistance to weathering of the modified bitumen. The use of oxidized bitumen in road construction became more widespread during the 1930s and 1940s, as the demand for improved road surfaces increased.In the decades that followed, the process of oxidizing bitumen was refined and improved, leading to the development of a wide range of oxidized bitumen products, including Oxidized Bitumen 75-35.

Usages of  Oxidized Bitumen 75-35

Oxidized Bitumen 75-35 has a variety of uses in the construction industry and is commonly used for the following applications:

Road Construction: Oxidized Bitumen 75-35 is used as a binder in the production of asphalt for road construction. It provides increased durability and resistance to weathering, which helps to extend the lifespan of roads and reduce maintenance costs.

Roofing Felts: Oxidized Bitumen 75-35 is used in the production of roofing felts, which are used to waterproof flat roofs and other low-slope structures. The material provides excellent weather resistance and durability, making it a popular choice for roofing applications.

Waterproofing Membranes: Oxidized Bitumen 75-35 is also used in the production of waterproofing membranes for use in below-grade applications such as foundations, tunnels, and basements. The material provides excellent resistance to water and other environmental factors, helping to prevent water intrusion and damage.

Pipe Coating: Oxidized Bitumen 75-35 is used as a coating for pipelines to provide corrosion resistance and protect against damage from the environment.Joint Filling: The material is also used to fill expansion joints in concrete structures, providing a flexible and durable seal that helps to prevent water intrusion and damage.

Soundproofing: Oxidized Bitumen 75-35 is used in soundproofing applications due to its high viscosity and ability to dampen sound waves.

Packing of Oxidized Bitumen 75-35

 Oxidized Bitumen 75-35 is typically packed in new steel drums or polybags, which are suitable for transportation and storage. The most common packaging sizes for oxidized bitumen are 150 kg drums and 25 kg polybags, although other sizes may be available depending on the manufacturer.The drums are typically coated with a rust inhibitor to prevent corrosion and ensure the quality of the bitumen during transportation and storage. The polybags are usually packed in cardboard boxes or shrink-wrapped for added protection.

It's important to note that proper handling and storage of oxidized bitumen are critical to maintaining its quality and performance. The material should be stored in a cool, dry place away from direct sunlight, heat sources, and moisture. It should also be protected from dust and other contaminants that can affect its properties.
