Abstract
This study aims at investigating an influence of alkali-silica reaction (ASR) on fatigue resistance of RC bridge deck. Firstly, using full-sized RC deck specimens, two types of ASR accelerated tests were performed by varying the environmental condition of ASR. Then, a wheel load trucking test was conducted focusing on the presence or absence of water on upper-surface of the specimen. In this experiment, the deflection and crack patterns of RC deck specimen in each number of trucking were measured, and the degradation of stiffness due to ASR and fatigue was evaluated by forced vibration test using small vibration device. As a result, it was revealed that the fatigue resistance of RC bridge deck by ASR depended on the environmental condition of ASR, which was assumed due to the introduction of chemical prestress by ASR, and the interaction of crack propagation and water action. Furthermore, the vibration test proved useful in evaluating the fatigue resistance of RC bridge deck by ASR.
