Abstract:
Advancements in electric vehicle (EV) adoption have driven demand for innovative charging solutions, including dynamic wireless power transfer (DWPT) systems that enable continuous in-motion charging. This study explores integrating a DWPT system within an instrumented flexible pavement through full-scale accelerated pavement testing. The mechanical evaluation, based on 75,000 passes of accelerated pavement testing, was examined through strain and rutting data. Condition assessments were conducted before and after traffic, including falling weight deflectometer (FWD) testing and static load evaluations. FWD results indicated reduced deflections after traffic, likely due to secondary compaction and waste heat generated by the DWPT mechanism. Deflection basin parameters revealed greater surface layer degradation in the areas surrounding the DWPT unit, while lower deterioration was found along the transverse edge, likely due to stiffness differences between asphalt and concrete. Asphalt strain gauges indicated steady increases in strain levels influenced by seasonal variations. Rutting measurements correlated well with strain data, showing higher rutting over the DWPT unit due to the reduced structural integrity of the thin HMA surface layer. While the embedment of the DWPT system influenced the pavement’s mechanical behavior, no visible distress was observed, indicating that the pavement performed similarly to conventional flexible pavements under controlled loading.
