Bitumen 115/25

bitumen 115-25

General description of bitumen 115/25

Bitumen 115/25 having a high softening point value by oxidation of base bitumens with medium penetration.Bitumen 115/25 has higher softening points and increased resistance to temperature variations compared to regular bitumen.

This makes it suitable for applications where greater durability and resistance to aging are required. It is often used in the production of roofing materials, adhesives, sealants, and pavement applications

How to produce bitumen 115/25?

Process for the production of bitumens of improved penetration value by oxidation of a bituminous mass comprising a base bitumen obtained as a residue of vacuum distillation of petroleum, wherein turbo-dispersion of a gaseous oxidizing agent is carried out in said bituminous mass at a temperature between 170° and 250° C., in which the gaseous oxidizing agent is dispersed in the bituminous mass in a proportion of between 0.1 and 1 Nm3 /h/ton of said base bitumen by contact with a turbo-disperser rotating at a speed of at least about 1400 r.p.m.

Uses of  bitumen 115/25

Oxidized asphalt 115/25 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 oxidized asphalt 115/25 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 115/25 include roofing, pipe coating, portland cement pavement, hydraulic applications, paint manufacturing.

Packing of  115/25

The ATDM is manufacturer of blown asphalt 115/25 in various packing including kraft bag, meltable plastic bag, drum and bulk blown asphalt 115/25 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached.

The ATDM blown asphalt 115/25 can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The oxidized asphalt grade 115/25 means softening point is 115°c and penetration is 25 desimillimiter is produced in compliance and conformity to ASTM standard and meets the following specification.

Guaranty/warranty of 115/25

ATDM guaranty the quality of blown bitumen materials 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 to ASTM/EN 13304:2009.
