• وصف: Bitumen is the residue or by-product when the crude petroleum is refined. A wide variety of refinery processes, such as the straight distillation process, solvent extraction process etc. may be used to produce bitumen of different consistency and other desirable properties. Bitumen based parings and roofings are subject to water runoff from rainfalls. Moreover bitumen is sometimes used to line water reservoirs. Bitumen is also used to line and cap hazardous waste sites -preventing rain water from permeating through the hazardous waste and from leaching into ground water.
