Refined bitumen is obtained using the distillation process; Such as bitumen from coal and petroleum products. Coal bitumen is a type of bitumen that is obtained by distilling coal tar. This type of bitumen has good adhesion and is used as insulation for underground pipes. Therefore, World class bitumen to export has been greatly improved by our company.

Soluble bitumen is obtained by dissolving pure bitumen in petroleum solvents. The type and quality of soluble bitumen depends on the quality of the original pure bitumen, the type and amount of solvent. The higher the amount of petroleum solvents in the dissolved bitumen, the greater its fluidity or viscosity. The percentage of solvent used in soluble bitumens usually varies from 20 to 50%. Soluble bitumen is used in road construction for surface coatings, infiltration, surface asphalt, cold factory asphalt or mixed asphalt on site, etc. Soluble bitumens are classified into the following three main groups according to the setting speed and the type of solvent:
Instant soluble bitumens
If gasoline and light solvents are used to dissolve pure bitumen, soluble bitumen is called quick-setting, because the solvent in the bitumen evaporates quickly shortly after the soluble bitumen is consumed, leaving the original bitumen.
Solution bitumen
Slow-moving bitumens are prepared by dissolving pure bitumen in kerosene and semi-heavy petroleum solvents, which have a slower and longer evaporation rate of solvent than gasoline.
Delayed bitumen solution
Delayed bitumens are obtained by dissolving pure bitumen in heavy petroleum solvents such as diesel or black oil. Like bitumen, these bitumens can be obtained directly from the distillation of crude oil.
Application of soluble backfill as a primer, surface coating and asphalt substrate
Primer
Provides adhesion between a layer of non-concrete material and a bitumen surface and its task is to connect the substrate surface by penetrating into the cavities to a depth of 5-10 mm. Also, the main primer coating must be able to impregnate and penetrate.
Cover surfaces
This type of bitumen is mostly used in countries where the temperature is relatively high and causes the bitumen to cover the surfaces for protection and to create the necessary adhesion for the next operation. The most grade of bitumen used in this field is MC3000.
Under the asphalt work
It is an adhesive coating and a very thin layer of bitumen that makes a good connection between the two layers. Make sure the asphalt and the layer below it have good adhesion. To use this type of bitumen, high viscosity must be used. For more information on bitumen size of molecules, visit our website.
Exporting top grade bitumen in 2020
Iran ranks seventh and fourth in the world among dozens of bitumen producing and exporting countries, respectively. Iran can meet 8.3% of global bitumen demand!
Bitumen pit is used in two areas of road construction and insulation. About 90% of the bitumen produced is used in the field of road construction and insulation costs account for only 10% of the bitumen consumption. But today, Exporting top grade bitumen in 2020 is facing a lot of growth, which is also a good currency for the country.
