What Is Oxidized Bitumen?
Oxidised bitumen is produced by passing air through a bitumen feedstock under controlled conditions. This produces a higher softening point bitumen with reduced susceptibility to change with temperature and greater resistance to imposed stresses. Applications include using in roofing materials, waterproof papers, electrical components and many other building and industrial products. Classification is normally by both penetration value and softening point specifications.
This material is also sometimes referred to as “BLOWN BITUMEN” and, in the USA, AIR-BLOWN ASPHALT Oxidized Bitumen or Blown bitumen grades are produced by passing air through the penetration grades.
