Bitumen, also known as asphalt or tar, is a viscous, black, sticky substance that is derived from crude oil during the refining process. It is a complex mixture of hydrocarbons and other organic compounds, predominantly containing polycyclic aromatic hydrocarbons. Bitumen is commonly used as a binding agent in road construction and maintenance due to its adhesive properties and ability to provide durability and flexibility to pavement surfaces.
