Abstract
The purposes of this study are to evaluate the applicability of design fatigue curve which takes the probability of failure into account, and to inspect the validity of application of Miner's rule for concrete pavement design. As the result of simulation for fatigue failure of concrete slab, it was found that the failure probability of concrete slab agree with the failure probability of design fatigue curve. From the results of fatigue test for specimens which cut off from in-service slabs, it was verified that the Miner's rule can explain the process of fatigue failure of concrete.
