Oxidized Bitumen by air blown asphalt:
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.
Blubber bitumen has a lower degree of penetration than pure bitumen . its softening-point is high. Also its sensitivity to temperature variations is low.
Symbolic of hard asphalt is R. For example R 80/25 bitumen means blown bitumen with degree of softness 80 centigerad and a degree of penetration is 25
Uses of Oxidized Bitumen:
Oxidized Bitumen have several usages in industry:
- Oil and Gas industries:
Coating materials for pipe lines and pipe joints of Oil Also Gas Pipelines.
- Electrical industries:
Sealant of wire coating
- Waterproofing industries:
Building roofing felts in factories and first materials components who are producing waterproofing roofing felt sheets
- Bitumen and Asphalt:
Road paving, Asphalt, constraction.
- Making Sound insulation layers.
- Car tires and lining.
PUB-LTD is oxidized asphalt manufacturer and multi face company based on Iran. In addition, We are structured into focused on oxidization of Bitumen division to serve the different needs of our customers worldwide. In addition, we are providing Blown Asphalt (Oxidized Asphalt_Blown Bitumen_Oxidized Bitumen_oxidized)in various grades including Oxidized BITUMEN 115/15 blown asphalt 95/25 oxidised asphalt 85/40 , bitumen 90/15 oxidized bitumen 90/40 bitumen 85/25 bitumen 75/25 pure petroleum bitumen 150/5 Hard asphalt or Hard bitumen and any other all grades of Oxidized Bitumen according to order.
Blown bitumen grades:
Blown bitumen grades (115/15 90/40 90/10 90/15 85/25 105/30 150/5 75/25) have wide range of usages. It uses in where there is expected minimum amount of moving in the joint. Their wide temperature range prevents bleeding in high temperature. It can also apply in industrial like roofing, flooring, mastic, pipe coatings, electrical usages.
Uses of oxidized bitumen:
Used for protection of under ground concrete,bridges,culverts,retaining walls,tanks surroundings,dams,conduits and decks.
Also apply in built up water-proofing 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.
Also it`s raw material to produce of water proofing stuff.
Oxidized Asphalt 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. It uses as rubberized property and preparing some elasticity to the roads.
