General description of oxidized bitumen 115/25
Bitumen 115/25 having a high softening point value by oxidation of base bitumens with medium penetration
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 oxidized asphalt 115/25

Packing of blown asphalt 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.
