| 中文摘要: |
| 通过对粉性土这种特殊类型土用作高等级公路底基层，进行稳定方法研究，通过试验证明，在粉质土中一起加入石灰、粉煤灰、水泥等外加剂，除强度满足设计要求外，其温缩系数与干缩系数比单独加入其他外加剂是最小的，能够减少道路裂缝，延长道路使用寿命，从而为广大使用者提供参考。 |
| 英文摘要: |
| In this paper, the stabilizing method of silt soil used for high grade highway base is studied. Experiments show that, adding lime, fly ash, cement and other additives in the silty soil not only makes it meet the design requirements, but the temperature shrinkage coefficient and shrinkage coefficient is the smaller, which can reduce road cracks, extend the road life, and thus provides a reference for the users. |
