摘要
In this paper, a new epoxy-based concrete for bridge expansion joint rapid repair (EJR) has been prepared, and the fatigue performance of the EJR and the repaired concrete members are investigated.The results show that the EJR has excellent fatigue performance compared with cement-based materials for rapid repair.There is no interface transition zone in the EJR, which means that the EJR has fewer internal defects.Based on an analysis of the stress-strain curve and energy consumption, the fatigue life equation of the EJR and repaired concrete members is established, which are suitable for the semilogarithmic form and the correlation coefficients of the linear fit are above 0.95.The investigation provides a reference for predicting the fatigue life of a repaired bridge expansion joint.
