摘    要:以广西兴六公路为例,提出了用稠度指标来评价膨胀土的含水量情况.在最佳稠度时,当用湿法重型击实标准检测土的无侧限抗压强度CBR满足设计要求时,弱、中等膨胀土是可以作为路堤填料的。并介绍了膨胀土填方材料的性质、控制要求和施工工艺要求。

关 键 词:路堤填料  膨胀土  重型击实  公路  填方  无侧限抗压强度  施工工艺  稠度  情况  含水量

Abstract:Taking the Xingye-Liujing highway in Guangxi province for an example, this article advices using the dense degree to estimate the moisture of expanding soil. When the moisture of expanding soil is appropriate, the low level and middling level expanding soil can be used as the road bank padding. At the same time, the result of compressive strength of no-indirect restrict measured by the humid heavy beat method must meet the designing requirement. Besides, the article introduces the quality of the road bank padding used by expanding soil, the requirements and construction techniques.
Keywords:expanding soil  subgrade filling  application  discussion
