| Abstract: | CA mortar is the most important component of flexible adjusting layer of ballastless slab track structure. In terms of the material physical and mechanical properties, durability and weather-durability of ballastless slab track of CA mortar, the paper elaborates its composition, structure and performance of the interaction, and points out the current ballastless slab track of CA mortar of freeze-thaw and aging of the mechanism of destruction, and puts forward the its mechanism and preventing measures. |
