Description of Oxidized Bitumen (Blown Asphalt) infrastructure, and industrial sector Oxidized bitumen, also known as blown asphalt, is produced by passing air through hot bitumen at elevated temperatures. This process alters the molecular structure of the bitumen, resulting in increased hardness, viscosity, and temperature resistance compared to conventional bitumen. Oxidized bitumen is commonly used in roofing, waterproofing, and paving applications due to its improved durability and weather resistance. It’s available …
