| description | To explore the effect of pore precipitation freezing in different saturated states on mechanical performance for drainage asphalt pavement, the study revealed the freezing behavior characteristics of pore precipitation in different saturated states by combining CT scanning, FEM simulation and mechanical tests. Firstly, the real spatial structure of drainage asphalt mixture was obtained through the CT scanning, and the corresponding FEM simulation model was established. Secondly, the process of pore precipitation freezing in different saturated states was simulated and analyzed, and its influence on the spatial structure of drainage asphalt mixture was obtained. Finally, the effect of pore precipitation freezing in different saturated states on drainage asphalt mixture was proved through mechanical tests. It is found that the effect of pore precipitation freezing on mechanical performance of drainage asphalt mixture is different under different saturated states. With the increase of saturation state, the influence of pore precipitation freezing becomes more obvious, and the difference of stress-strain distribution in spatial structure for drainage asphalt mixture is more prominent. The study explains how pore precipitation freezing in different saturated states affects the mechanical performance for drainage asphalt pavement, providing a theoretical basis for enhancing its durability. |
