Abstract: Since reinforced concrete (RC) deck slabs are usually damaged by cyclic live load, it is necessary to monitor the deck slab for operation and maintenance purposes. Acoustic emission (AE) is an excellent technique, which can be used for continuous monitoring and detecting fatigue damages of RC structures. First, the AE was applied for evaluating fatigue damage of RC deck slab with truck wheel traveling test in laboratory. The results showed that there was a correlation between the AE energy and damage degree of the slab. Thus, it was able to presume the damage degree by AE energy. In the next step, a test by vehicle with clear mass in a in‐service bridge was performed. The results of the laboratory and in‐service bridge tests imply that the damage degree of RC deck slab are able to evaluate by AE energy.
