blown asphalt

blown asphalt 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 blown asphalt is a highly insulating material with good adhesion properties with respect to almost any solid material.

ATDM is blown asphalt manufacturer and multi face company based on Iran. We are structured into focused on oxidization of Bitumen division to serve the different needs of our customers worldwide.
We are providing Blown Asphalt (Oxidized Asphalt_Blown Bitumen_blown asphalt_oxidised bitumen)in various grades including blown asphalt 115/15 blown asphalt 95/25 oxidized asphalt 85/40 , bitumen 90/15 oxidised bitumen 90/40 bitume 85/25 bitum 75/25 pure petroleum bitumen 150/5 Hard asphalt or Hard bitumen and any other all grades of blown asphalt according to order. Throughout the world, more than 8 types of bitumen that is produced depend on the type of weather conditions one of them is blown asphalt.

blown asphalt grades (115/15 90/40 90/10 90/15 85/25 105/30 150/5 75/25) are suitable for sealing saw cuts and joints where there is expected to be the minimum amount of moving in the joint. Their wide temperature range prevents bleeding in high temperature applications. blown asphalt can also be used in industrial applications like roofing, flooring, mastics, pipe coatings, electrical applications. OXIDIZED ASPHALT IS MANUFACTURED FROM CRUDE PETROLEUM BY SUITABLE REFININING TO CONFORM TO THE APPLICABLE REQUIREMENT.

USES:

• USED FOR PROTECTION OF UNDER GROUND CONCRETE, BRIDGES, CULVERTS, RETAINING WALLS, TANKS SURROUNDINGS, DAMS, CONDUITS, DECKS, ETC.
• OXIDIZED ASPHALT, TYPE R (GRADE 115/15) HAS GOOD RESISTANCE FOR VERTICAL & SLOPED SURFACES UNDER DIRECT SUNLIGHT IN THE TEMPERATURES EXCEEDING 50O C.
