| 摘 要： | 对膨胀土进行不同掺和量的石灰和粉煤灰改性处理，研究了改性膨胀土的物理性质、压实特性、压实后的强度和胀缩性变化。指出了改性膨胀土路基填料有别于一般粘性土，用击实试验的最佳含水量作为压实控制标准是不合理的，并基于试验结果提出了改性膨胀土路基压实的含量水控制标准。

| Abstract: | The lime and fly ash were added to the expansive soil at different percentage to stabilize. Testing specimens were subjected to physical properties, compaction, CBR, free swell and swell capacity tests in laboratory. The study shows that a change of expansive soil texture takes place when it is mixed with lime and fly ash, and it is irrational for the expansive soil mixed with lime and fly ash to make the optimum moisture content state from compaction test as a rule for controlling compaction in construction field. Based on the test,the standard of controlling compaction for the subgrade filler with stabilizing expansive soil by lime and fly ash is presented. |
