In this study, wheel load running fatigue test was conducted on a slab specimen produced with concrete replacing crush sand with blast-furnace slag fine aggregate. By comparing with the results of a similar wheel load running fatigue test on concrete using crushed sand, the influence due to the difference in fine aggregate for concrete was evaluated. It was confirmed that concrete using blast-furnace slag fine aggregate has enough fatigue durability compared to concrete using crushed sand. It was also confirmed that concrete using blast-furnace slag fine aggregate can be evaluated with the proposed S-N prediction formula by considering the effects of the main reinforcement and transverse reinforcement and sorting out the values from the past experiments.
