Geothermal Energy for Bridge Deck and Pavement Deicing—A Brief Review

Geothermal energy is characterized as renewable, sustainable, clean (i.e. zero carbon emission) and directly used energy, which has been widely used in many engineering applications, such as ground source heat pumps (GSHP), geothermal energy piles (GEP), and soil borehole thermal energy storage (BTES). This paper presents a literature study of geothermal energy for deicing approach pavement slabs and bridge decks. The background with respect to the related applications of geothermal energy is firstly introduced. The working principle and design criteria of geothermal systems are then presented for future field applications where the soil thermal conductivity is a key parameter that can be studied by a newly developed thermo-time domain reflectometry (TDR) probe. Several case studies in Europe and Asia are also reviewed to further demonstrate the feasibility and applicability of this innovative technology. The long term cost-benefit is finally analyzed, and some recommendations for field implementation are also provided.
