Recently, various damages such as corrosion of rebar, scaling on concrete pavement and environmental deteriorations caused by using the chloride-containing deicer have been reported. To solve these problems, several substitute deicers have been developed by other researchers. However, studies on evaluation of performance for the developed deicers have been limited in the basic laboratory testing. It is necessary to establish the resonable and systematic test procedure for evaluating the deicing performance. In this study, rational and practical test methods were set up through literature review and deicing performance of Eco-Friendly Deicer(EFD), which is a kind of low chloride-containing deicer developed by our research group, was evaluated by the presented test methods. As results of the laboratory tests, initial deicing performance of EFD was similar with that of Pre-Wetted Salt(PWS) which has been used in highway deicing and it was verified by executed field tests in twice that EFD had passable deicing performance compare with PWS.
