In order to reveal the effect and mechanism of vibration mixing technology on the strength of cement stabilized macadam,the unconfined compressive strength and indirect tensile strength tests of cement stabilized macadam based on the traditional and vibration mixing technologies were carried out.Then,the mesostructure of the cement stabilized macadam was analyzed by the scanning electron microscope.There sults show that the unconfined compressive strength and indirect tensile strength of cement stabilized macadam are improved by the vibration mixing technology, while the variation coefficient is decreased, and the homogeneity is improved. Moreover, the stabilization time of the strength is shortened, and the improvement of the strength at low cement content is more obvious. At the ages of 7,28 d, the hydrate is much more and distributes more uniformly in the vibration mixing cement stabilized macadam, and mang network structures with high toughness are formed,which will improve its strength. At the age of 90 d,columnar ettringite crystals go into the aggregate, making the structures denser and the strength higher.
