Abstract
Field tests with carbon fiber heating wire (CFHW) embedded inside concrete slab were performed to present the alternative heating material capable of avoid the adverse effects of traditional de-freezing salt on the structures and environment. The CFHW was inserted into the concrete slab in the shape of 'ㄷ' to improve the heat superposition and the temperature on the surface was measured using iButton. The results showed that the temperature where the CFHW's were faced with each other increased to above zero after 12-hour at outdoor air temperature of $-6^{\circ}C$. Comparatively, the temperature slightly increased where the CFHW was embedded on one side because the heat was not superimposed. Hence, it can be said that the CFHW is a suitable heating material to prevent the concrete road from being frozen.
