Blown Bitumen is industrial bitumen which is dark, petroleum residue modified by the oxidation process. Blown Bitumen is produced by passing air through bitumen under controlled temperature conditions. Its consistency ranges from highly viscous to solid.
Blown bitumen grade has technical advantages such as durability, flexibility, water resistant and chemical stability. There is different grade of blown bitumen as 115/15 90/40 85/25 85/25 90/15 95/25 75/25 150/5 105/30
Oxidized bitumen is a specially formulated plastic for construction. Oxidized bitumen characterized by being a product of great thermal amplitude. Oxidized bitumen has flexibility to cold, has no sag at high temperatures and has good adhesion. It can be applied in any kind of work. Oxidized bitumen is available in different grade as 115/15 90/40 85/25 85/25 90/15 95/25 75/25 150/5 105/30
