Deicer spreading is typical winter road management operation. In domestic, pre-wetted spreading method using calcium chloride solution and solid sodium chloride has been applied. However, chloride-containing deicer may cause fatal effect to corrosion of rebar and scaling on cement concrete pavement surface with freezing - thawing cycles. Also, it reduces durability and performance of pavement by reducing concrete strength. In this study, the damage caused by deicers on concrete pavement was investigated by accelerated scaling test and compressive strength test, comparing specimen using CMO with specimens using existing deicers such as calcium chloride, sodium chloride and low-chloride-containing deicer. As a result of tests, the damage on concrete pavement by CMO was negligible compare than the damage by existing deicers.
