One-dimensional rheological models of asphalt-aggregate mixtures
Asphalt-aggregate mixtures constitute basic component for the road pavements construction. The fundamental problem in the procedure of pavement design is to elaborate the appropriate constitutive model suited for the structuaral behavior modeling within wide range of mechanical and environmental loadings. This paper deals with the analysis of one-dimensional rheological models of asphalt aggregatemixtures. We have begun with classical viscoelastic Burgers scheme along with its alternative variants. Then the proposal of an original rheological model including plasticity was given. The differential constitutive relationships of such a model are presented in the paper. The results of computer simulations are also visualized.
