AB - Thermomechanical behavior of hot mix asphalt (HMA) is considered. Its highly  irregular microstructure is covered by the hierarchical approach. A brief  survey of endochronic thermodynamics precedes constitutive consideration. Two  constitutive models are discussed: classical Perzyna’s approach and tensor  representation based approach. The second is superior due to its possibility  to cover properly diverse multiaxial nonproportioal stress-strain histories.  However, due to availability of experimental data the first model is applied  to rutting problem through Abaqus FEM code with material user subroutine  developed by the authors. Vakulenko’s thermodynamic time appropriate for  aging is incorporated. Hyperelasticviscoplastic behavior is considered and  some preliminary results are presented.
