Due to the fact that highways are the most used transportation mode in our country and the weather conditions are hard during the winter season, various problems are encountered on the roads where terrestrial climate is seen and these problems threaten traffic safety. It poses significant risks especially in road sections such as tunnels, bridges and vertical kurve and also causes material loss accidents. The methods used in the struggle with icing are divided into two classes as active and passive methods. Passive methods are applied in two ways; chemical and physical. Chemical methods are the application of a variety of chemicals to the pavement surface with the aim of preventing and eliminating icing. These chemicals appear to cause some damage to environment, roads, metal parts of vehicles and traffic sign boards and do not seem to provide the desired performance. Physical methods are carried out by removing snow and ice from the coating surface by using work machines. Using this method, both equipment workforce and time losses are occurring. Hydronic heating systems, which are active methods, circulate a heated fluid through a pipe network located below the pavement layer to melt snow and ice that accumulate in the coating layer. By using geothermal spring waters, which are clean and inexpensive resources as heated liquids, it is aimed to be prevented without creating snow and ice without causing environmental damage, human health and financial loss. In this paper, the characteristics of anti-icing systems and hydronic anti-icing systems used in roads, what kind of materials are used in such systems and their contributions to traffic safety are mentioned.
