Grading Design of Recycled Aggregate Cement-Stabilized Gravel Based on Rotary Compaction

The traditional design method for semirigid materials is unsuitable for the design and construction of modern road recycled building materials due to the high water absorption property of construction waste recycling aggregates. Therefore, this study compares the mix design results of the traditional and rotary compaction methods of recycled aggregate cement-stabilized gravel. Test results indicate that the optimum water content obtained using the rotary compaction method is smaller than that obtained using the traditional method, and the dry density index of 80 compaction times complies with the design results of the traditional method, whereas the strength of the specimen is higher than that of the hydrostatic specimen. When cement content exceeds 7%, the strength of the material is mainly influenced by the cement, and the forming method minimally affects strength. The rotary compaction method is more suitable for the design of cement-stabilized recycled aggregates. The optimum water content and the maximum dry density of the cement-stabilized aggregates have a stable number of compaction.
