The deicing work is usually considered as a main part of the highway maintenance activity in during the winter season. The deicing includes the physical method which removes snow with tools and the chemical method which removes the snow with deicing material. When removing snow using deicing material, excessive deicing material will cause the environmental and budget problems. If the deicing materials are used less than the required amount, the snow will remain on the road surface. For these reasons, the adequate usage of deicing materials is important. In this research, the performance of deicing material has been evaluated and the amount of deicing material has been determined according to the amount of snow through the laboratory and the field experiments. Also the adequate usage of deicing material has been determined by 130kg/km-lane on two lane road.
