Oxidized Asphalt is a solid or semi-black solid material and gradually liquid when heated, oxidized asphalt is predominant content bitumen, asphalten , malten (oils) and aromatic resins. The oxidized asphalt or blown asphalt is producing in different softening point and penetration like as 115/15 90/40 85/25 85/25 90/15 95/25 75/25 150/5 105/30
Oxidized Bitumen is a peculiar amorphous material which is generally in liquid form when discharged by oxidation plants at a temperature ranging from 240°-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.
