| 摘 要： | 在高速公路施工中使用弱膨胀土进行路基填筑时，要对膨胀土进行改性处理。石灰作为一种有效外掺剂，可使膨胀性降低、强度显著提高。含水量和CBR强度作为衡量路基土性能的重要指标，在道路设计和施工中具有重大意义。通过研究路基土的CBR强度与含水量和膨胀土之间的关系，可为今后科学合理地进行路基膨胀土施工提供有力的科学依据。

| Abstract: | During the highway construction, low expansive soil has to be treated before subgrade. As an efficient adulteration, lime can reduce the expansibility and content and CBR are important indexes for evaluating the perfarmance significant in highway design and construction. Research of the relationship expansive soil can provide scientific foundation for further reasonable subgrad filling the enhance the strength. Moisture of subgrade soil, which are of CBR, moisture content and e expansive soil construction. |
