The purpose of this study is to pursue an approach to developing the snow melting systems on pavement, which utilizes the treated sewage. Snow melt on pavement provides a means of transportation for all the trip makers, including transportation-disadvantaged people, which can be viewed as a civil minimum in snowy and icy areas. In this snow melting system treated sewage with relatively high temperature is conveyed through pipes under target pavement and melts snow by heat conduction. Though other systems have been conventionally adopted for snow melting, this system can be a viable option in terms of cost. To demonstrate the feasibility, we first set the objective of snow melting capacity on a risk management basis, and confirmed treated sewage had sufficiently high temperature. Next, we conducted an experiment to measure heat capacity provided by treated sewage using the experimental pavement and pipes. We also showed this system has cost advantage over the conventional in case of a larger area. Finally, we pointed out the problem of scale formation in the pipes and the countermeasures.
