OXIDIZED BITUMEN 85/40

OXIDIZED BITUMEN 85/40

Oxidized (Blown) Bitumen is produced by either continuous or Staggered Blowing Process. Heated Penetration Grade bitumen under controlled environment is blown with air which controls the oil content in the bitumen while it oxidized. The different grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges.
