BITUMEN is a petroleum product formed by the process of distillation of crude petroleum. It is available both in solid and liquid form. It is providing a good grip to the tyres as compared to the coal tar. Bitumen is available in three types that is; Rapid Setting, Slow Setting and Medium setting. In the modern era, we used bitumen instead of Coal Tar because Coal Tar is Carcinogenic.
COAL TAR; Coal tar is derived from the coal.It is a black viscous liquid used as a sealing agent in old roads making all over the world. It is not used in the current era, due to the carcinogenic product. It is produced through the process of destructive distillation in the absence of air. Coal Tar not provide enough grip to the tyres of the vehicle and heat up quickly causes wearing out of tyres.
