Recently, energy consumption has increased and due to this green house gas emission also increased and it causes extreame whether. In fact, the frequency of heavy snowfall and heavy rainfall is increasing every year. According to this result, roads exposed to environmental loads at all times and the freezing phenomena such as black ice are frequently occurred. Especially, in case of black ice, it is difficult to distinguish it by the naked eyes of the traffic users and difficult to secure sufficient braking distance, which is a direct cause of traffic accident. In order to prevent freezing of the road surface during the winter season, chloride-based snow removers and heat transfer pipes are used. However, these method noted secondary pollutions and economic efficiency as disadvantages.
Therefore, it is essential to develop a new snow removal system that improves the disadvantages of existing snow removal methods. Carbon fiber sheets are widely used in aviation, sports and medical fields because of their high strength, light weight, high conductivity and exothermic properties. Therefore, this study was conducted to develop a new method of road surface snow melting system, which is applied as a heat source by weaving carbon fiber. The heat behavior of concrete specimens with carbon fiber sheet were evaluated under various conditions. Also evaluated durability of embedding materials with different properties can be caused of low freezing-thawing resistance and tensile strength. As a result, the carbon fiber sheet was embedded into the road as a heat source, and the possibility of applying the carbon fiber sheet as a snow melting system was confirmed.
