Abstract

A procedure that could be used for rapid evaluation and screening of asphalt aggregate mixes is presented. The procedure could also be adopted to evaluate the rutting propensity of a mix, taking into consideration traffic level and the pavement location. The underlying assumption in this approach is that permanent deformation is primarily a plastic shear flow phenomenon at constant volume, occurring near the pavement surface and caused by shear stresses appearing below the edge truck tires. Intrinsic to this procedure is the assumption that most permanent deformation occurs during the hottest days and as a result of a heaviest trucks. That assumptions stems from laboratory observations that asphalt concrete mixes exhibit strong plastic behavior, described by a plasticity function that exhibits kinematic hardening.
