Bitumen, Material : Tar

Bitumen is also known as Asphalt, is a sticky, black and highly viscous liquid or semi-solid form of petroleum. The primary use (70%) of asphalt/bitumen is in road construction. It is principally obtained as a residual product in petroleum refineries after higher fractions like gas, petrol, kerosene and diesel, etc., are removed. It is a black or dark brown non-crystalline oil or viscous material having adhesive properties derived from petroleum crude either by natural or by refinery processes.

It is generally used for civil engineering works like constructions of roads, runways and platforms, water proofing to prevent water seepage, mastic floorings for factories and Warehouses, canal lining to prevent erosion, dump-proof courses for masonry, tank foundation, joint filling material for masonry etc.
