Dear Tom, In India, peope buy drums of bitumen in a hardware shop and use the same in making wooden poles termite proof, in making asphalted areas in their own yards and also in waterproofing the house tops. Huge quantities of bitumen are used by the Government in road construction. I was told that bitumen is obtained as a byproduct when the raw petroleum is fractionally distilled to obtain fractions like kerosene, diesel, petrol, LPG etc. Is the tar, which is a component of pyrolysis gases same as bitumen? Yours A.D.Karve
