| Abstract: | Existing studies show that the cement stabilized semi-rigid base using recycled： concrete aggregate （RCA） can meet the requirements of the standard specification of the semi-rigid base material aggregate. Hence, It＇s an effec- tive way to recycle the waste cement concrete pavement slab that using RCA as a cement stabilize semi-rigid base mate- rial. In this paper, the durability performance of cement stabilized semi-rigid base material using recycled concrete ag- gregate with wetting-drying test method to simulate natural environment has been studied. Results show that the optimal cement ratio is 4.5%, and the optimal maintaining period is 21 days. |
