Oxidized bitumen by air blown asphalt:
Bitumen generally is liquid. It discharged by oxidation at 240° to 300° C. So it becomes solid or pasty. This blowned bitumen known as Oxidized Bitumen. 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.
Oxidized Bitumen Grades:
GLOBALLY BITUMEN is oxidised asphalt manufacture. Also its multi face company based on Iran. We are structured into focused on oxidation Bitumen division to serve different needs of our customers worldwide. We are providing Blown Asphalt(Oxidized Asphalt_Blown Bitumen_Oxidized Bitumen_oxidized bitumen)in various grades including Oxidized BITUMEN 115/15, 95/25, 85/40, 90/15, 90/40, 85/25, 75/25, 150/5 Hard asphalt or Hard bitumen and any other all grades of Oxidized Bitumen according to order. Furthermore, there is 8 types of bitumen. Producing process depend on type of weather.
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. It also apply in industies like roofing, flooring, mastics, pipe coatings, electrical applications.
Uses of oxidized bitumen
Oxidised asphalt specially uses in the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement ,crack seal also in repairmen, civil works, roofing, construction industries, sealing and insulating buildings, adhesive, construction materials additive, dust-binding, coating, insulating and impregnating agent, make rubber and plastic products. The blown asphalt 115/15 products are for paving, roofing.
Also used in asphalt based paints for corrosion protection of metals, in lining public works structures, adhesives in electrical laminates, base for synthetic turf.
However typical uses for oxidized asphalt 105/15 include roofing, pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing.
It Used for protection of under ground concrete,bridges,culverts,retaining walls,tanks surroundings,dams,conduits and decks.
Oxidized Bitumen uses 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 115/15 has good resistance for vertical 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.
Blown Asphalt, as crack filler of asphalt:
Bitumen oxide in addition using as crack sealer depend on road and standard. Also depend on climate and minimum – maximum temperature of day and night. Oxidized bitumen has very high viscosity. After preparation crack and clean area. Use it directly, will get dry very soon and stick to the asphalt. Blown asphalt as rubberized property, preparing some elasticity to roads.
