| Research Abstract |
About the mortar used in an overlay strengthened method, the influence of the water was related to the bond strength estimated by the material strength and interface roughness. In this study, it was suggested that an anchor rod was adopted to prevent the concrete cover separation, and the resisting mechanism was shown. A traveling wheel load test was carried out for a real scale bridge deck to inspect an effectof the overlay strengthened method, and then the prediction equation of a fatigue life for punching shear failure was shown.
