Oxidized Bitumen 85/25 (or Blown Bitumen 85/25) is a semi-strong and midrange grade of this classification. Oxidized Bitumen R85/25 assembling is finished via air blowing delicate Bitumen (***** Grades, Bitumen 60/70). This grade of ***** Bitumen is the base and natural substance for most bituminous items. The technique under controlled conditions gives bitumen flexible properties more than different sorts of bitumen.
Oxidized Bitumen 85/25 is delivered by either a Continuous or Staggered Blowing Process. Warmed ***** Grade Bitumen under a controlled climate is blown with air which controls the Oil Content in the Bitumen while it oxidized. The various grades for fit applications delivered are assigned by two numbers to demonstrate the mid-points of their conditioning point and infiltration ranges.
