A viscous, dark brown to black liquid or solid made up of heavier hydrocarbons and their derivatives is known as bitumen. The majority of Bitumen comes from petroleum refineries, where the bottom distillation column products are further processed to produce a fine grade of bitumen using equipment like solvent deasphalted, oxidizers, blenders, and other units.Asphalt, also referred to as bitumen, is a dark, sticky combination of hydrocarbons that is either produced naturally or as a byproduct of petroleum distillation. It is employed in many different contexts, such as road construction, where asphalt concrete is made by mixing it with aggregate particles and using it as a binder. Along with other things, the production of insulation, glue, and roofing felt also uses waterproofing materials. Bitumen is an important raw material in the construction and industrial sectors for building water tanks, dams, and bridges due to its high viscosity, stickiness, and water-resistance characteristics.
Penetration grade, oxidised bitumen grades, cut back bitumen, bitumen emulsion, and polymer modified bitumen are the five kinds of bitumen depending on their characteristics. Bitumen is a thermoplastic and hydrocarbon mixture with a tarry smell and temperature-dependent stiffness. It is available in bulk and drums, and the link between bitumen's temperature and stiffness depends on the source of the crude oil and the refining process. Modified Crumb Rubber Bitumen (CRMB) is bitumen that has had some of its physical properties altered, such as by adding crumb rubber, making it more resistant to weather changes, temperature fluctuations, and heavy traffic loads while also requiring less maintenance and providing improved driving comfort.
