In this study, the experimentally observed rate-dependent viscoplastic hardening-softening of hot mix asphalt (HMA) is modeled using Perzyna's flow rule and a rate-dependent yield stress function. The yield stress function, which is adopted from the convolution integral in linear viscoelasticity, is
