Oxidized bitumen 115/15 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air.

The most oxidized bitumen usable grade is bitumen 115/15 and 70% of our capacity is dedicated for this grade.

Oxidized Bitumen is a peculiar amorphous material which is generally in liquid form when discharged by oxidation plants at a temperature ranging from 240° to 300° C., and becomes solid or pasty at ambient temperatures.  

While being relatively hot, it is viscous, whereas when in pasty or solid state it possesses a fair degree of elasticity.  

Both in liquid and in plastic or solid form oxidized bitumen is a highly insulating material with good adhesion properties with respect to almost any solid material.
