China oxidized bitumen supplier

There is alot of refinery in Qingdao of China to produce oxidized bitumen but unfortunalety there is alot of impurity into Chinese oxidized bitumen.
The impurity comming from Carbonate calcium and other filler which increase weight of the product and meltiong of the oxidized bitumen will become very hard and needed alot of energy to heat and melt it.

In china oxidized bitumen facories producing below blown asphalt grades:

• Oxidized bitumen 75/25
• Oxidized bitumen 85/25
• Oxidized bitumen 95/25
• Oxidized bitumen 90/40
• Also medium grade oxidized bitumen 90/10
