Use of Geothermal Energy for De-icing Approach Pavement Slabs and Bridge Decks, Phase II

项目名称：	Use of Geothermal Energy for De-icing Approach Pavement Slabs and Bridge Decks, Phase II
摘要：	De-icing using geothermal energy can provide TxDOT a better alternative than the existing method of de-icing with sands and/or salts. This research project will address the topic with a primary focus of comprehensive synthesis study. As a part of this synthesis, the available literature on geothermal energy along with success application case studies on the use of geothermal energy for bridge decks and pavement deicing applications will be compiled. The review of geothermal underground structures will be focused on Underground Thermal Energy Storage (UTES,) which is used to inject or extract heat into/from underground soil for seasonal cooling and heating needs. A preliminary finite element analysis of bridge de-icing using geothermal energy will also be performed, using typical Texas soil and climate conditions to demonstrate feasibility, along with potential cost-benefit analysis of the recommended geothermal de-icing system for field application. Recommendations will be made on candidate geothermal structures and bridge deck/pavement heating systems for field demonstration studies, as a part of follow up validation studies.
