Abstract: The use of electrically conductive heated concrete systems in winter conditions is an interesting alternative to extend the life of structures and to ensure the mobility and safety of road users. By replacing some conventional components of concrete, it is possible to increase its conductivity sufficiently to release heat when electric current passes through it. Using this type of system in strategic points can be an option to replace techniques currently used for snow and ice removal, which are bad for the environment, are not effective, cause damage to structures and are very expensive. Nevertheless, the success of such a system requires a good elaboration of the electrically conductive concrete mix design and a configuration of electrodes that releases heat uniformly. Sensor automation increases the energy efficiency of the system by activating the latter only when the need arises, i.e. under snowfall, freezing rain or freezing fog conditions. The main objective of this research project is to develop an automated snow and ice melting system using the previously mentioned concrete and electrodes. In this thesis, the development of electrically conductive concrete and mortars mix designs will be presented, in addition to the development of an electrode configuration that meets criteria of safety and energy consumption previously established by the searchers. These laboratory steps will be followed by tests in real winter conditions on a 1.1m² prototype installed on Laval University’s campus. The successful results confirm the innovative side and commercial potential of the developed system.
