The condition of ten roadways constructed between February 1983 and Hay 1984 has been evaluated with respect to distortion, cracking, raveling, rutting, and overall condition. These observations have been correlated with laboratory measurements of rheological and chemical properties of the refinery liquid from which the roadway was made. Rheologic parameters include penetration, ductility, and viscosity. Chemical measurements include elemental analyses, fractionation into asphaltenes, oils, and resins, infrared and C-13 nuclear magnetic resonance spectra, molecular size of asphalt components by high performance liquid chromatography, and solvent solubility
