ABSTRACT: Snow accumulation on bridge decks during winter causes tremendous inconvenience for drivers and traffic accidents. A traditional approach for snow melting and de-icing of bridge decks is to use salt which can lower the freezing point of water to prevent the formation of ice. Unfortunately, this method can induce some problems. Salt will not only be ineffective for snow melting or de-icing if temperature falls below -3.9 °C, but also penetrate down to the slab and accelerate the corrosion of concrete and steel used in a bridge deck. The pile foundations designed to support the loads of bridge structures can also be used to provide renewable energy heat source for hydronic heating system used for snow melting. In this paper, the feasibility study of snow melting system using geothermal energy pile is performed for Edmonton and Winnipeg based on the typical weather conditions during snowfall and their underground conditions.
