The production of this material is done by distilling crude oil and this type is also called petroleum bitumen or distillation. Its oil type includes two stages of crude oil distillation in the distillation tower. The first stage of distillation involves the separation of light petroleum materials, including: gasoline and propane, and at this stage the pressure is close to one atmosphere. The next step involves the separation of heavy materials such as diesel and kerosene, which is done at a pressure close to vacuum pressure, and in the final process a mixture of very fine asphaltene particles remains, which is immersed in a grease-like liquid like malt.
In addition to the production process in refineries, this material is produced in mineral form and in nature in the form of gradual conversion of crude oil and evaporation of its volatile materials after many years. This type is more durable than other petroleum types and can also exist pure in nature, such as Behbahan Bitumen Lake in Iran or Bitumen Lake in Trinidad, USA.
Bitumen, as an asphalt additive, has the main consumption in road construction and the second consumption is for insulation industry. in general, the common uses of this material can be summarized in the following uses:
– Road construction
– Different Industries
– insulation
– Electrical insulation
