In order to study the influence of different vibration intensity on the performance of cement stabilized gravel. Vibration mixing tests of cement stabilized gravel with 5% cement factor were carried out under different vibration intensity, Through the preparation and maintenance of cylindrical specimen and the mid-beam specimen, The unconfined compressive strength test and the drying shrinkage test were carried out, Vibratory mixing can significantly improve the strength of cement stabilized gravel and reduce the level of intensity variation, As the vibration intensity increases, the increase range of specimen strength increases first and then decreases, Considering the mechanical reliability factors, It is reasonable to increase the strength of the material when the vibration intensity is D = 2 ∼ 3. Vibration mixing can improve drying shrinkage property of cement stabilized gravel, the vibration mixing reduces the water loss rate of the specimen at the later stage of shrinkage, with the increase of vibration intensity, the variation of dry shrinkage coefficient becomes smaller during shrink age period, and the coefficient of dry shrinkage decreases with it, Therefore, the greater the vibration intensity, the better drying shrinkage property of cement stabilized gravel. Vibration mixing can improve the mechanical behavior and cracking resistance of cement stabilized gravel simultaneously, it has a wide application prospect.
