In this report an evaluation is made of the potential end uses of an oil produced from Asphalt Ridge tar sand by wet forward combustion. The oil is evaluated with respect to its potential to produce a specification-grade asphalt and an aviation turbine fuel. To accomplish this the oil was vacuum distilled to produce a distillate and a residue. The distillation residue meets all of the ASTM D-3381 Table 1 specification tests for an AC-10 asphalt. However, the 135/sup 0/C (275/sup 0/F) viscosity is low when compared with the more stringent ASTM D-3381 Table 2 requirements. The residue also has an unusually low aging index. This indicates not only that it may not set properly, but also it may be resistant to rapid age hardening. The results from successive freeze-thaw cycling indicate that the residue, when coated on appropriate aggregates, is comparable to or better than some petroleum asphalts coated on the same aggregates. Freeze-thaw cycling to failure is an indirect measure of the resistance of an asphalt-aggregate mixture to moisture-induced loss of strength. The distillate of the thermally produced oil represents about 50 wt % of the oil. The chemical and physical properties of the distillate are better than those of the original bitumen and the thermally produced oil. Combined gas chromatographic/mass spectral analysis of the neutral fraction from the distillate indicates it is composed of predominantly aromatic structures. The aromatic structures are primarily of the 2- and 3-ring type and the saturate structures are primarily of the 3-ring type. It is believed that upon hydrogenation this distillate could be a source of high-density or endothermic aviation turbine fuels.
