Dynamic on-road charging of vehicles can be done by conductive means, whose implementation require the presence of elements in the pavement, potentially affecting its durability. Some prototypes tested on site and in laboratory showed different mechanisms of damage: rutting, interface debonding and thermal cracking. Including different materials in an asphalt concrete (AC) can generate differential stress fields that can lead to premature failure. A thermal test was developed to simulate the behaviour of AC under daily thermal solicitations. This paper focuses on the development of a numerical simulation able to represent the stress field evolution in the AC. A Generalized Maxwell model coupled to WLF equation represented the thermo-viscoelastic behaviour of the AC under such conditions. This model was implemented into a FEM software named Cast3m®. First results show a stress concentration in the AC just under the groove. According to the design used for implementing ERS infrastructures, stress levels remain under acceptable values as to avoid damage. |
