With a total length of approximately 280 kilometres, the Tokyo Metropolitan Expressway handles an average daily traffic volume of around 1.15 million vehicles and is used by roughly 2 million people every day. The structures have been exposed to the severe traffic conditions and with the passage of time certain parts have begun to show sign of deterioration. In particular, there has arisen an anxiety that the defects of existing decks, which are directly influenced by live loads, will increase. The proper maintenance of the decks is an important issue. The aim of this study is to verify the effects and to establish rational design methods for carbon fiber sheet bonding. This paper introduces the method and present results of the fatigue test of RC decks with reinforced carbon fiber sheets.
