Abstract [en]

The continuous growth in road transportation demands further development towards sustainable strategies. The electrification of road infrastructure (commonly referred to as ‘e-Road’) to enable wireless charging solutions for Electric Vehicles (EVs) is arising as one of the most promising and yet challenging alternatives for the future mobility by road. In this context, the introduction of charging facilities in the pavement structure and its adequate performance from an infrastructural perspective is determining for the successful implementation of these systems.This study aims to evaluate the structural integrity of e-Roads, considering the embedment in the pavement of a solid module denominated ‘Charging Unit’ (CU) in which the charging facilities are assumed to be installed. To do so, the critical locations of an e-Road pavement structure were identified through computational modelling for its further representation as small-scale e-Road samples in the laboratory. Afterwards, this structure was subjected to different loading conditions using mechanical hydraulic devices and compared with conventional road samples produced under the same conditions. Finally, e-Road samples were scanned with X-ray Computed Tomography (CT) prior to, during and after loading for additional inspection. Results provided valuable learnings of the potential mechanisms of failure of such structure and a better understanding of the e-Road infrastructure.
