Characterization of Pavement Performance Based on Field Validation Test Site Data Interpreted by an Asphalt Composition Model of Binder Oxidation

This study presents straightforward and simple correlations between the measured phase angle of binder materials extracted from the top slice portion of recovered pavement cores derived from test pavement sites at the time in the life cycle of the pavement when cracking is just beginning to occur and cumulative cracking that is noted several years after this time. The interpretation of these correlations lies in the observation that the phase angle may be a compositional measurement of the brittle elastic material which builds up in asphalts during oxidations, formally referred to here as oxidation product asphaltenes. Therefore, a dynamic suspended phase mass fraction is defined in terms of the phase angle.
