Bitumen types
Natural bitumens: They are a group of bituminous materials that are created naturally under the influence of atmospheric factors and the passage of time and are used without the need for distillation methods, and are very diverse in terms of composition and properties.
Tar pitch: A hard, black substance that is the residue of the distillation of coal tar. The freshly broken surface is shiny, and when heated, it melts with a rapid decrease in viscosity, and its melting point depends on the method of production.
Petroleum bitumens: These are the types of bitumens that originate from crude oil. These bitumens are solid and semi-solid bitumens that are obtained directly from the distillation of crude oil or by additional operations such as air blowing, and have more applications and higher consumption than other types of bitumen.
