Fatigue tests under running wheel loading on RC slab test specimens with the top surface reinforced by overlaying the SFRC were conducted and evaluated fatigue resistance and predicted the timing of secondary repair about surface damage of RC slab. As result, that is derived which evaluated the number of equivalent cycles that is derived D-N curve with between the damage value associated with the increase in deflection and the number of equivalent cycles by running tests under running wheel loading, damage factor of moist condition concrete, and the number of equivalent cycles for reinforcement consider for revision factor of design quality. Therefore, this study is suggested S-N curve consider for design quality 1964, 1968 years enabled to predict of the timing of secondary repair.
