Configuration of Electrodes for Electrically Conductive Concrete Heated Pavement Systems

This study investigates the effects of the type and configuration of embedded electrodes on resistive heating performance of an electrically conductive concrete (ECON) heated-pavement system (HPS). Three ECON slabs—an ECON slab with perforated galvanized steel angle electrodes, an ECON slab with steel rebar electrodes, and an ECON slab with perforated galvanized steel angle electrodes with an isolation layer—were designed and constructed. The resistive heating performance of the slabs was evaluated by measuring the electric current and ECON slab surface temperature at specific points during the application of voltage. The results revealed that the performance of the ECON slab with perforated galvanized steel angle electrodes was marginally changed when an isolation layer was used, so with respect to construction practice and cost considerations, an isolation layer is not deemed to be necessary for constructing large-scale ECON heated pavements. Electrical current measurements can be used for evaluating the conductivity and the heating capability of the ECON slabs.
