The amount of snow due to global warming and climate change has recently increased. The effective management of snow removal materials will be required. First, on the basis of domestic winter temperature, it is not necessary to get a baseline to less than the freezing point of –52°C for the calcium chloride(CaCl2) of 30%.. In terms of cost comparison between calcium chloride(CaCl2) and sodium chloride(NaCl), the calcium chloride(CaCl2) is 2 to 3 times more expensive, and the supply of the calcium chloride(CaCl2) is not produced in domestic country and is in the conditions that have to imports all needed. Accordingly, the effective use scheme of snow removal materials should be considered to multifaceted ways. Thus, the objective of this study is to develop effective method and to replace from calcium choride(CaCl2) to sodium chloride(Nacl) solution in the current snow removal operating system that uses a pre-wetted salt spreading method. The effective method that equals to the quality of the existing snow removal materials was developed in this study through performance tests for deicing chemicals, corrosion test of steel and freezing and thawing tests of concrete.
