Development of a damage viscoelastic model using the thick level set approach to fracture: 1D modeling and comparison to uniaxial tension stress tests on bituminous specimens

The present paper deals with the development of a mechanical model coupling damage and viscoelasticity for applications related to fracture in bituminous materials and structures. The behavior of these materials is highly thermo-sensitive and depends on the loading rate. Currently, there is no consensus on a modeling approach able to capture their behavior to fracture for a wide range of temperature and loading conditions. This is an objective...
