Bitumen

Bitumen is a viscous, black, and sticky substance that is a byproduct of crude oil refining. It is commonly referred to as asphalt or asphalt binder. Bitumen is a complex mixture of hydrocarbons and is predominantly composed of polycyclic aromatic compounds. It is a vital component in the construction industry, primarily used as a binder in asphalt for road construction and maintenance.

Bitumen has excellent adhesive and waterproofing properties, making it suitable for various applications. It is commonly used in the production of asphalt concrete for road surfaces, as well as in roofing materials, waterproofing membranes, and sealants. Bitumen is known for its durability and ability to withstand heavy traffic loads and harsh weather conditions.

The properties of bitumen can be modified by adding additives or blending it with other materials to achieve desired characteristics such as improved elasticity, flexibility, or resistance to extreme temperatures. Different grades of bitumen are available, each with specific properties suitable for various applications in the construction and infrastructure sectors.
