Bitumen

The common binders used in bituminous road constructions are road tars and Bitumen. Bitumen has gradually replaced road tar for road construction purposes mainly because of its greater availability as compared to road tars. It is principally obtained as a residual product in petroleum refineries after higher tractions like gas, petrol, kerosene and diesel, etc., are removed generally by distillation from suitable crude oil. Indian standard institutions define Bitumen as a black or dark brown non-crystalline soil or viscous material having adhesive properties derived from petroleum crude either by natural or by refinery processes.

IndianOil refineries at Panipat, Mathura, Koyali, Haldia and CPCL produce grades Bitumen 80/100; Bitumen 60/70; Bitumen 30/40; Bitumen CRMB and Bitumen Emulsion- 'Indmul'. It is available both in packed and in bulk.
