Production Process

Process by which compressed air is blown into vacuum bottom residue, typically at 230–260 °C in a reactor. This process results in complex reactions (such as Dehydrogenation، Polymerization، Oxidation). different grades for suited applications produced Due to ratio of air blowing

Air Blowing Bitumen

Production of bitumen product in Iran and world by blowing method and Straight run method.

The Air Blowing Bitumen is produced by process of vacuum Bottom (VB) and air in the reactor. and due to the control of the process conditions, different grades are produced.

This Bitumen is applied in construction and maintenance of:

  • Highways
  • Airport runways
  • Pedestrian Ways
  • Car parks
  • Racetracks
  • Tennis courts
  • Roofing
  • Damp proofing
  • Dams
  • Reservoir and pool linings
  • Soundproofing
  • Pipe coatings
  • Cable Coatings
  • Paints
  • Building Water Proofing
  • Tile underlying waterproofing
  • Newspaper Ink Production
  • And many other applications

Cutback Bitumen

 

Cutback Bitumen is by adding controlled amounts of petroleum distillates such as kerosene. This is done to reduce the viscosity of the bitumen temporarily so it can penetrate pavements more effectively or to allow spraying at temperatures that are too cold for successful sprayed sealing with neat bitumen. The materials used to cutback bitumen will evaporate after application to leave the remaining material similar in hardness to the original bitumen

Modified Bitumen

This type is produced according to customers' request, Pavements designed and constructed for heavy duty traffic and extreme weather conditions require specially designed engineered Bitumen Grades. By changing the characteristics of normal bitumen with change of process condition or and the addition of a modifier such as polymer
