Research on Modified Compaction Test Method for Cement Stabilized Macadam
This paper uses the indoor test and test road verification method to test and detect the modified compaction specimen and the vibration forming specimen,and studies the influencing factors of the strength of cement stabilized macadam and the influence degree.The influencing factors mainly consider the forming method,cement dosage,mineral aggregate gradation and compaction degree standard.It is found that the forming method is the main factor affecting the strength of cement stabilized macadam,the maximum dry density of vibration compaction mixture is 0.020 g/cm3 higher than that of modified compaction specimen,and the optimum water content is 12%lower than that of modified compaction specimen;optimizing the mineral aggregate gradation and cement dosage is helpful to improve the road performance of cement stabilized macadam;appropriately improving the compaction degree standard can ensure that the compacted cement stabilized macadam has compactness and flatness.
