A Numerical Analysis Tool To Evaluate Pavements Integrated With Dynamic Wireless Power Transfer Technology

As electric vehicles (EVs) continue to gain market share in the U.S., the integration of dynamic wireless power transfer (DWPT) systems into pavements has emerged as a promising solution to address range anxiety and infrastructure limitations. However, the structural implications of embedding DWPT technology into roadways remain insufficiently explored. This dissertation presents the development and application of a numerical analysis tool to evaluate the mechanical performance of flexible pavements containing embedded charging units (CUs). A series of finite element models, validated with full-scale experimental data, were used to assess the influence of axle loading, material properties, layer configurations, bonding conditions, temperature, and vehicle speed on pavement responses. Parametric studies were performed to identify critical design factors impacting fatigue and rutting life. Results show that CU inclusion can improve or degrade pavement performance depending on bonding quality and design conditions, with CU-HMA interface stiffness emerging as a dominant factor. The findings support the advancement of design strategies for electrified road infrastructure and provide a framework for evaluating structural responses prior to large-scale deployment.
