| 摘 要： | 石灰改性土在公路工程建设中得到广泛应用，研究者也积累了较多经验，但施工控制参数中石灰土的含水率确定方法还值得商榷。就公路工程中石灰改性膨胀土的施工最佳含水率确定方法进行了探讨，提出了与目前公路部门相关试验规程和技术规范中确定石灰稳定土最佳含水率不同方法，认为石灰改性膨胀土的施工最佳含水率应以由击实试验确定的最佳含水率大3 %左右为宜。

| Abstract: | Although lime-treated soil has been widely used in the road construction with many application experiences, the determination of the optimum water content in the parameters control of construction still needs to be deeply discussed. In this paper, the method to determine the optimum water content of lime-treated expansive soil in the road engineering is analyzed; and a new method, different from the corresponding testing standards and technical specifications for the ministry of communications, is presented; and it is illustrated that the optimum water content in the lime-treated soil should be 3% larger than the one determined by the compaction test. |
