摘　　要：本文结合云南省某高速公路项目建设过程中使用振动击实方法进行水泥稳定级配的配合比设计与施工控制中。对级配碎石的级配控制、最佳含水量、拌和加水量的控制,以达到最佳的施工效果。通过与重型击实方法的对比,使用振动击实方法可以更好选择材料级配并降低水泥剂量。但振动击实所确定的最佳含水量往往是理论状态的含水量,可以根据天气情况和运距适当调整含水量,以达到较好的和易性满足施工要求。During the construction of cement stabilized gravels,vibrating compaction test was applied on the mix design and construction control to determine the gradation of gravels,optimum water content and mixing water content as to achieve best quality.Comparing the results of both vibrating and modified proctor compaction test,it shows that vibrating test can effectively determine the cement content and gradation,but the mixing water content need to to be adjusted according to the weather condition and transport distance.
