Bitumen is a thick, black, sticky substance derived from crude oil. It is primarily used in the construction of roads and roofing materials due to its waterproofing and adhesive properties. Bitumen is often mixed with aggregates to create asphalt, which provides a durable surface for highways and parking lots. In addition to road construction, bitumen is also utilized in various industrial applications, such as sealing and insulation. Its ability to resist water and weathering makes it an essential material in the construction industry, contributing to the longevity and safety of structures like roofs and pavements.
