 Oxidized bitumen 90/15


Description of production of oxidized bitumen 90/15

In BAKHTAR Bitumen as the producer of bitumen, at the bitumen production reactor, during the air acting, the mixture of the two Vacuum Bottom (VB) and Vacuum Silas (VS) feedstock is put under a special degree of pressure and temperature between 200-300˚C of which the hydrogen atoms content in bitumen molecular oxidize to oxygen of air, and obtains with higher hydrocarbons polymerization reaction that has lower penetration and higher softening points than the primary pure bitumen. This kind of bitumen 90/15 has the softening point of 90 and permeability of 15.
BAKHTAR Bitumen Industrial Group Company guaranty the quality of BAKHTAR Bitumen Oxidized bitumen 90/15 and is ready to prove its quality issues by inspection of international inspectors to check quality and quantity of the blown asphalt 90/40 to be in conformity with ASTM regulations and standards before loading and also during production.

APPLICATIONS of oxidized bitumen 90/15

BAKHTAR Bitumen Oxidized bitumen 90/15 is utilized in the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement, crack seal and repairmen, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating and impregnating agent, make rubber and plastic products. BAKHTAR Bitumen the Oxidized asphalt 90/15 products are mainly used for paving, and also used in asphalt-based paints for corrosion protection of metals, in lining public works structures, adhesives in electrical laminates, base for synthetic turf, typical uses for oxidized bitumen 90/15 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. Oxidized bitumen 90/15 is applied in insulation and isolation bitumen membrane sheet. Also, Car undercoating Automobile industry is specially required for Blown Asphalt. Vehicle undercoating material is based on Bitumen. Bitumen provides excellent waterproof, dust proof and noise proof for automobile undercoating. BAKHTAR Bitumen Oxidized bitumen is a specially formulated plastic for construction. Oxidized bitumen characterized by being a product of great thermal amplitude. BAKHTAR Bitumen Oxidized bitumen has the flexibility to cold, has no sag at high temperatures and has good adhesion. It can be applied in any kind of work. Oxidized bitumen is available in the different grades.

How to Apply oxidized bitumen 90/15

BAKHTAR Bitumen Oxidized bitumen 90/15 must be heated with double temperature against the softening point to be able to have flow and viscosity. Before applying oxidized bitumen 90/15, clean and dry the surface from any loose particles, formwork, curing products, irregularities, slurry, and any dirt.

Storage/handling Conditions of oxidized bitumen 90/15

BAKHTAR Bitumen guarantees its Blown asphalt 90/15 for the period of 10 years in the condition of  multi-time heating and cooling situation, please refer to MSDS standards for further information.

Packing of oxidized bitumen 90/15

BAKHTAR Bitumen different types of packing is available according to customer’s purpose and requirements to make them convenient. BAKHTAR Bitumen is the manufacturer of bitumen 90/15 in various packing formats including Kraft bag, meltable plastic bag, drum, and bulk oxidized bitumen 90/15 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. BAKHTAR Bitumen oxidized bitumen 90/15 can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The bitumen grade 90/15 means the softening point is 90°c and penetration is 15 desi millimeter is produced in compliance and conformity with ASTM standard and meets the specification as below:
