The purpose of this article is to verify the hypothesis that asphalt behaviour can be properly described using the visco-hypoplastic constitutive model. For this purpose, asphalt specimens were subjected to traditional geotechnical tests (triaxial and oedometer tests) at different temperatures and at varying strain rates. These test results were used to verify the applicability of the constitutive model and to determine the model parameters and their temperature dependency. The performed tests and numerical analyses demonstrated that the visco-hypoplastic material model can be used effectively in the numerical modelling of rolled asphalt behaviour.
