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.
