This project seeks to establish the technical foundation necessary to deploy geothermal pavement and bridge deck heating systems in Pennsylvania as a viable alternative to chemical deicing. The core objective is to design and experimentally verify a scalable geothermal heating module that couples pavement, subsurface geology, and atmospheric conditions through physically grounded scaling relationships, enabling adaptation across climates, soil conditions, and structural configurations. Recognizing that prior work has focused primarily on the pavement-side of closed-loop systems, this research addresses the full thermal loop, including subsurface heat extraction efficiency and long-term performance. Through literature synthesis, scaling analysis, laboratory testing of novel and conventional ground loop configurations, and bridge deck heating experiments, the project will identify technically and economically feasible approaches—particularly for retrofit applications. The effort will culminate in candidate module designs and a high-level techno-economic evaluation of three pilot sites, providing a roadmap for future field deployment of geothermal deicing systems.
