Gao, L.-L.; Jiang, Z.-G and Wei C.-X., 2019. Fatigue analysis of rubber powder and fiber concrete in coastal areas. In: Gong, D.; Zhu, H., and Liu, R.

Due to insufficient durability of pavement caused by environmental corrosion in coastal areas, a modified concrete material with higher durability is proposed in this paper. Through tests, fatigue failure process of C (concrete) and RPFC (rubber powder and fiber concrete) is studied by analyzing the maximum fatigue strain and fatigue residual strain based on the laws of cyclic load-strain variation of concrete with different mixing amounts of fiber and rubber powder under different stress ratios. According to the law thatεthe total strain varies with N the number of cycles of C and RPFC trabecula with different mixing amount of fiber and rubber powder under different stress levels, the maximum fatigue strain and fatigue residual strain are extracted to study their variation curves on cycle ratios. Thus, a law can be concluded that the strain amplitude varies with the cycle ratio of C and RPFC trabecula with different mixing amount of fiber and rubber powder under different stress levels, which can provide reference for the design of coastal pavement structure.
