<p>The validity of application of Miner's rule to fatigue durability prediction of highway bridge RC deck slabs subjected to random wheel loading was investigated. The cumulative fatigue damages of the stepped incremental amplitude loading fatigue test data were numerically evaluated by applying Miner's rule with the S-N curves obtained by the running wheel fatigue test under constant amplitude loading. All the cumulative fatigue damages of the test results indicated higher than 1.0 and consequently applicability of Miner's rule to fatigue durability prediction of highway bridge RC deck slabs was verified on the safe side.</p>
