In 2004, Japan's Ministry of Land, Infrastructure, Transport and Tourism conducted an inspection and surveyed the bridges constructed on major routes, there through most severe damages are associated with the deterioration damages caused by fatigue of the RC slabs.
Therefore, in this study, an analysis was conducted on the damaged state of aging bridges, and cases of maintenance and reinforcement in accordance with the damaged state were examined. Furthermore, the reinforcement effect and fatigue resistance of the CFS in regard to the RC slab was evaluated through a fatigue test under a running wheel load which reproduces the fatigue damage through the reciprocating motion of the wheel load. Thereafter, the adhesive reinforcement method that integrates the concept of self-healing repair methods for a smart CFS undersurface was examined.
