Roads are the nerve of our country. Bitumen has been used for binding purpose in flexible pavements. But the diminishing fossil fuel will force us to go with another binder than bitumen and this problem can be greatly resolved by taking coal tar into consideration. Coal tar although a by product of the process of carbonization of coal finds various uses in our day to day life. It might have been thrown off as a waste material but its use has been defined by various researchers since very old times. Most coal tar is obtained as a by-product in pyrolysis of coal to coke for steel making. At the beginning of the 1980s world output of coal tar was about 18m. tonnes, of which 14m. tonnes came from coke production. Production of coal tar has fallen considerably in recent decades. Globally about 10-20% is used directly as fuel, road materials and in surface coatings for corrosive environments. Often, though, the functional requirements are so specialised that the requisite tar is produced by mixing pitch and suitable tar distillates. Most coal tar is distilled.
