Oxidized Bitumen

      Oxidized bitumen

      Oxidized bitumen (also known as blown bitumen) is manufactured by blowing air through bitumen. To be more specific, in the air blowing method of bitumen production, the air in 190 to 200 c is blown to the substance and the oxidized or air blown asphalt is produced. Due to the air blowing process, oxidized bitumen comes with more rubbery properties. Among unique specifications of blown bitumen are flexibility, increased durability, and resistance to water.

      Blown bitumen grades broadly used as an anti-slip layer compound in the industry. It is also applicable to roofing and waterproofing industries, piling industry, sound dampening, the automotive industry, and so on. As oxidized bitumen is hard, its softening point is much higher than regular bitumen. Also, its Penetration Index is higher than a regular one.
