Nowadays asphalt mixture is the most used material in the construction and reconstruction of roads. It is used for its advantages, such as availability of materials, flexibility and no need for dilatation. However, the asphalt mixture has one disadvantage, namely temperature sensitivity. At different temperatures it exhibits different physical-mechanical properties. For a better understanding of the physical-mechanical properties of the asphalt mixture, we can use complex rheological models. Complex rheological models can describe the viscoelastic behaviour of the asphalt mixture with a high prediction. Laboratory tests are required to determine input values for complex rheological models. The article is focused on the analysis of asphalt mixture in the indirect tensile strength test and compare with numerical solution.
