Highway Pavement Surface Icing and Traffic Safety: A Review

Due to the truth that highways are the most used transportation mode in our country and the weather conditions are hard at some point of the winter season, various issues are encountered at the roads wherein terrestrial weather is seen and those problems threaten traffic safety. It poses good sized dangers in particular in road sections including tunnels, bridges and vertical curve and also reasons material loss accidents. The methods used within the problems with icing are divided into training as energetic and passive strategies. Passive strategies are implemented in methods; chemical and physically. Chemical strategies are the utility of a variety of chemicals to the pavement floor with the intention of stopping and casting off icing. These chemical substances appear to motive some damage to environment, roads, metal elements of cars and traffic sign forums and do no longer appear to offer the favored overall performance. Physical methods are executed by means of putting off snow and ice from the coating floor with the aid of using work machines. Using this technique, each equipment staff and time losses are happening. Hydronic heating structures, which can be active methods, flow into a heated fluid via a pipe network placed below the pavement layer to melt snow and ice that collect in the coating layer. By the use of geothermal spring waters, which are clean and less expensive resources as heated drinks, its miles aimed to be prevented without creating snow and ice without inflicting environmental damage, human health and financial loss. In this paper, the traits of anti-icing structures and hydronic anti-icing systems utilized in roads, what type of substances are utilized in such structures and their contributions to traffic protection are cited.
