General description of oxidized bitumen 95/25
Oxidized bitumen 95/25 are less temperature sensitive than bitumen obtained by mixing of particular fraction. oxidized of bitumen result in partial dehydrogenation of asphaltenes which creates long chains of asphaltenes molecules by polymerization and condensation reaction. Harder bitumen 95/25 is produced by oxidization and desired quality of hard bitumen cannot be produced from too soft raw material by oxidization .
Uses of oxidized asphalt 95/25
Oxidised asphalt 95/25 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 asphalt 95/25 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 95/25 include roofing, pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing.
Packing of blown asphalt 95/25
The ATDM is manufacturer of blown asphalt 95/25 in various packing including kraft bag, meltable plastic bag, drum and bulk blown asphalt 95/25 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. The ATDM oxidised bitumen 95/25 can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The oxidized asphalt grade 95/25 means softening point is 95°c and penetration is 25 desimillimiter is produced in compliance and conformity to ASTM standard and meets the following specification.
Guaranty/warranty of blown bitumen 95/25
ATDM guaranty the quality of blown bitumen 95/25 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.
