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.
ATDM is oxidised 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_Oxidized Bitumen_oxidised bitumen)in various grades including Oxidized BITUMEN 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 Oxidized Bitumen 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 Oxidized Bitumen.
Blown bitumen 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. Oxidized bitumen can also be used in industrial applications like roofing, flooring, mastics, pipe coatings, electrical applications.
Oxidized asphalt is manufactured from crude petroleum by suitable refining to confom to the applicable requirment.
Uses of oxidized bitumen
Used for protection of under ground
surroundings,dams,conduits and decks.
Grade of oxidized asphalt can be used in built up water proffing system.
As a MOP coat for damp proofing.
Excellent bond and adhesive.
Raw material of mastic,primer and enamel.
Oxidized asphalt, type R 115/15 has good resistance for vertiocal and sloped surfaces under direct of sunlight in the temprature exceeding more than 50C.
Blown asphalt is as raw material to produce of water proofing stuff.
Oxidized bitumen is as crack filler of asphalt
Oxidized bitumen using as crack sealer depend on road and standard also depend on climate and minimum and maximum temprature of day and night.Oxidized bitumen has very high viscosity and after preparation of the crack and clean the cracked area using directly the oxidized asphalt and very soon will get dry and stick to the asphalt.Oxidised asphalt as ruberized property and preparing some elasticity to the roads.
How to apply oxidized bitumen?
Clean the surface before application and prime with asphalt primer, do not use emulsion asphalt as primer. Apply oxidized asphalt hot with lubbard or mop, apply felt or woven fabric when asphalt is hot, to be sure to have a good felt or woven fabric saturation.Do not use oxidized asphalt on wooden roof. Do not apply hot oxidized asphalt when is raining.
