Recently, a great social damage has been caused by the sargassum homeri, which has flowed from China in the Jeju and Namhae coasts. In this study, biopolymer was prepared by using sargassum homeri and applied to bridge pavement concrete. The performance of chloride ion penetration resistance of the bridge pavement concrete made of biopolymer was evaluated. As a result, excellent penetration resistance performance was shown.
