bitumen 85/40

General description of bitumen 85/40

Generally, the bitumen 85/40 is industrial asphalt essentially assessed by the technology of production, the relative concentration of resins, and asphaltene. The respective components in the bitumen particular role giving a synergistic performance to the bitumen. Asphaltene is the heaviest and responsible components for a non-newtonian character of Oxidized Asphalt , and they have a direct influence on the softening point and the rigidity of the bitumen. The resins promote good adhesion of bitumen to the surface of the minerals and of ductility (elasticity). Saturates and aromatics are responsible for the rheological property of the bitumen, such as viscosity.

Uses of bitumen 85/40

 Oxidized Asphalt bitumen 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 oxidized asphalt 85/40 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; typical uses for oxidized asphalt 85/40 include roofing, pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing.

Packing of bitumen 85/40

The ATDM is manufacturer of oxidized bitumen in various packing including kraft bag, meltable plastic bag, drum and bulk blown asphalt 85/40 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. 

Guaranty/warranty of 85/40

ATDM guaranty the quality of blown bitumen 85/40 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.
