General description of oxidized bitumen 90/40

Bitumen 90/40 is mostly use in Morocco and spraying on the concrete for the isolation and waterproofing application.It is high adhesive medium softening point and maximum penetration in all grades of blown asphalt.some times bitumen 90/40 using to mix with penetration grade of bitumen to make high viscosity bitumen.

Uses of oxidized asphalt 90/40

Oxidised bitumen 90/40 uses 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, coating, insulating and impregnating agent, make rubber and plastic products. The blown bitumen 90/40 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 it is typical uses for roofing, pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing.

Packing of blown asphalt 90/40

The ATDM is manufacturer in various packing including kraft bag, meltable plastic bag, drum and bulk from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. The ATDM can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The bitumen 90/40 means softening point is 90°c and penetration is 40 desimillimiter is produced in compliance and conformity to ASTM standard and meets the following specification.

Guaranty/warranty of blown bitumen 90/40

ATDM guaranty the quality of bitumen with arrangement of international inspector to check quality and quantity of the bitumen on each shipment during the loading to vessel and controlling the production by QC team via batch test report before shipping. ATDM guaranty the quality to meet with ASTM/EN 13304:2009.
