In order to improve the engineering application prospect of vibration mixing cement stabilized macadam, the performance of vibration mixing cement stabilized macadam and the compaction performance of base course are studied in this paper. The proportioning scheme of cement crushed stone stabilized soil is designed, and the proportioning of cement stabilized crushed stone is established by compaction method and testing compressive strength. Through the indoor test, the 7-day and 28-day unconfined compressive strength of ordinary mixing and vibration mixing are compared. The results show that the 7-day strength is increased by 38.6% and the 28-day strength is increased by 32.5%. The compaction test of ordinary mixing and vibration mixing cement stabilized macadam base is carried out. The research results show that the compactness of vibration mixing cement stabilized macadam after rolling for one time and final rolling is increased by 1.5% and 3.1% respectively. The research shows that the improvement of compaction technology of cement stabilized soil pavement under vibration mixing can improve the performance index of pavement and can be popularized.
