Oxidized Bitumen is produced by either Continuous or Staggered Blowing through soft bitumen/flux mixtures under controlled conditions. British Standard grades (BS 3690) are normally designated by two numbers representing the mid-points of their softening point and penetration ranges. Oxidized Bitumen grades are: 75/25- 75/35-85/25-85/30-85/40-90/10-90/15-90/40-95/25-105/15-105/35-115/15

Blown grade bitumen (Oxidized) is widely used as an anti-slip layer compound in the piling industry, for manufacture of roofing felts, for sound dampening felts and under carriage sealant in the automobile industry, electric cable joint protection, joint filling compound, sealant compound and many others. It€™s main advantages are:

• Durability

• Flexibility

• Water Resistant

• Chemical Stability

Production Process:

1. Bitumen heating to 265-270 °C

2. Transferring melted bitumen to blowing towers

3. Blowing air to bitumen

4. Cooling melted bitumen with water

5. Packing
