In this study, the results of impact loading tests were evaluated to determine whether the thick plate theory, which is based on the three-dimensional elasticity theory, is applicable to the maintenance of bridge deck slabs. As a result, it was shown that it is possible to confirm the effect of reinforcement and to grasp the progress of deterioration by comparing the results with calculated values. The results of the impact loading tests are considered to be consistent with the thick plate theory due to the effect of the vibration-damping rubber placed at the weight drop position of the testing machine.
