BITUMEN: ITS NATURE, CHARACTERISTICS, MANUFACTURE, TRANSPORT AND ECONOMIC ASPECTS

LE BITUME: CONSTITUTION, CARACTERISTIQUES, FABRICATION, TRANSPORT, ASPECTS ECONOMIQUES

Bitumen is obtained by treating the heaviest fraction of raw petroleum. It is divided into: residual bitumen and blown bitumen. The former - mainly used in road construction and hydraulic operations - is applied either hot for coating aggregates or in the form of blown bitumen or emulsions. The latter type is nearly exclusively used for industrial purposes mainly waterproofing. The manufacture of bitumen necessitates the choice of relatively heavy crude. Residual bitumen can be obtained by means of: direct distillation, distillation and mixtures, distillation and light blowing, from asphaltic bitumen. Blown bitumen is obtained by air-blowing of selected bases from distillation; the object of this operation is to reduce its susceptibility to temperature variations. Bitumen is delivered in France from 20 refineries, often hot in liquid form in insulated tankers. Sometimes coastal depots are supplied by 1500 ton coasters and river depots by barges. A small percentage is delivered by tank wagons to which heating devices are attached. /TRRL/
