Shale-oil obtained by retorting oil shale from the Green River formation in Colorado contains an appreciable amount of asphaltic material. This paper describes a preliminary laboratory study of this material. Series of asphaltic products of different consistencies were prepared experimentally by various petroleum refining processes, such as vacuum distillation, cracking, air blowing, and propane precipitation. The properties of these products were then measured by common asphalt tests, and the results were compared with those obtained for corresponding products from petroleum. In general, the study showed that asphaltic products of different consistencies can be prepared from Colorado shale oil. As might be expected, the properties of these shale-oil asphalts were somewhat different from those of asphalts from petroleum, particularly with respect to solubility, distillation, ductility, temperature susceptibility, and possibly wax content. To obtain products that meet specifications for petroleum, particularly with respect to solubility, distillation, ductility, temperature susceptibility, and possibly wax content. To obtain products that meet specification for petroleum asphalts, it would be necessary to adjust or alter several properties of the shale-oil asphalts. No attempt was made in this study to prepare shale-oil asphalts or roads oils that meet current specifications for products from petroleum or to determine the performance of the shale-oil asphalts under service conditions.
