Oxidized bitumen grades

Oxidized bitumen grades produced by blowing hot air into vacuum towers and is a petroleum product, a high molecular weight hydrocarbon that includes oil, resin and asphaltene. produced by blowing hot air into vacuum towers and is a petroleum product, a high molecular weight hydrocarbon that includes oil, resin and asphaltene. In the characteristics of oxidized bitumen grades, the presence of 5 to 30% asphaltene in the bitumen makes the bitumen hard, and in blown bitumen or oxidized bitumen, due to the increase in the amount of asphaltene in its structure, the blown oxidized bitumen is harder than normal bitumen. be more In the analysis of oxidized bitumen R90/15, R120/15, Bitumen R115/15, R10/20, the ASTM test (bitumen permeability degree), which is an international test, indicates the type of bitumen oxidized or blown in different grades.

Oxidized bitumen grades applying

The abbreviation of blown oxidized bitumen is R, for example, if bitumen is called R85.25, it means that it is blown bitumen with a penetration degree of 25 hundredths of a millimeter and a softening point of 85 degrees Celsius, wherever the word R is in front of the bitumen specifications, it indicates that the bitumen is oxidized. Oxidized bitumen normally used for sealing roofs, bathroom, covering subsurface of pavements, flooring, pool angels, pounds edges and some other wet areas indoor and out door of buildings, houses and using a lot in constructions and overhauling of buildings as an important sealer. Oxidized bitumen manufacturing in pure shape by using vacuum bottom as raw material and can be produced by mixing vacuum with Gilsonite powder or natural bitumen, based on order and different using which will be specified by the customer.

Oxidized Bitumen is packing in 25 kg sacks normally and exporting. Some other packing such as wooden or carton boxes and putting on pallet, shrink wrap and strapping are possible as well. Faragam company Blown Asphalt is producing and supplying by the best quality from pure raw material under international standards and supervision.
