BAKHTAR Bitumen Oxidized asphalt 90/10 

General description of oxidized asphalt 90/10

BAKHTAR Bitumen Oxidized bitumen 90/10 (in another word, oxidized bitumen 90/10, blown bitumen 90/10) is Semi Solid grade of pure petroleum bitumen manufactured by air-blowing through an asphalt flux. Special physical properties of its grade can be used in different applications in the construction business. BAKHTAR Bitumen Oxidized bitumen  90/10 is based on petroleum bitumen which is made by oxidized asphalt 60/70 by hot air. The numbers manifest the midpoint of the material’s softening point and penetration degree accordingly. The softening point value is measured by the Ring and Ball method as determined by ASTM D36 regulations and standards. The penetration value is in 1/10 mm as determined by IP49 or ASTM- D5.
BAKHTAR Bitumen Company is ready to let the international inspection companies to check the quality and quantity of BAKHTAR Bitumen Oxidized asphalt 90/10 during production and also as pre-delivery inspection before loading to  containers and BAKHTAR Bitumen guarantees that the quality of its products completely is based on ASTM Standards.

Applications of oxidized asphalt 90/10

BAKHTAR BITUMEN Oxidized asphalt 90/10 is normally applied in chemical, fuel, lacquers, varnishes, paint paper-pulp-board, textile processing, road construction, pavement, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, crack seal and repairmen, construction materials additive, dust-binding, insulating and impregnating agent, make rubber and plastic products. BAKHTAR Bitumen asphalt 90/10 products are for paving. 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 asphalt 90/10 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. asphalt 90/10 is using insulation and isolation bitumen membrane sheet. Also, Car undercoating Automobile industry is specially required for Blown Asphalt. Car industry undercoating material is based on Bitumen. Bitumen provides excellent waterproof, dust proof and noise proof for automobile undercoating.

How to Apply oxidized bitumen 90/15

BAKHTAR Bitumen Oxidized bitumen 90/10 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 90/10

BAKHTAR Bitumen guarantees its Blown asphalt, oxidized bitumen 90/10 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 90/10

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 90/10 in various packing formats including Kraft bag, meltable plastic bag, drum, and bulk oxidized bitumen 90/10 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. BAKHTAR Bitumen oxidized bitumen 90/10 can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The bitumen grade 90/10 means the softening point is 90°c and penetration is 10 desi millimeter is produced in compliance and conformity with ASTM standard and meets the specification as below:
