Evaluation of the shrinkage crack resistance of cement-stabilized aggregate by predicting the crack spacing
Source abstract
Abstract
Shrinkage cracks are a major issue in the manufacture of cement-stabilised aggregate (CSA) bases. This study proposes a novel mechanical method to predict the stress and crack spacing caused by shrinkage in CSA bases. Its effectiveness was found to be 71% by using field data collected from several expressways in Jiangsu Province, China. The predicted maximum crack spacing was used to evaluate the shrinkage crack resistance of CSA with different cement contents, gradations, and forming methods. The results suggest that for a specific gradation, an optimal cement content exists that leads to the best shrinkage crack resistance. The shrinkage crack resistance of a large stone base course (LSBC) filled with CSA was found to be 30% less than that of a typical gradation. Moreover, the shrinkage crack resistance of CSA specimens was improved significantly by vibration compaction forming compared with static pressure forming.
