低液限粉性土用于路面底基层施工的探讨

Discussion on the application of low liquid limit silt in pavement subbase construction

公路工程的特点决定了使用土类的多样性;沿海地区多有粉性土,其塑性指数在7-12之间,仅用石灰、粉煤灰来进行综合稳定,早期强度较低,成型质量较差,难以完全达到规定的稳定性要求,这就要采取一定的技术措施来加以改善,掺入适量的水泥进行综合稳定就是针对粉砂土的不利因素提出的一种有效措施。

The characteristics of highway engineering determines the diversity of soil types; more silt in coastal areas, the plasticity index between 7-12, only with lime, fly ash comprehensive stability, low early strength, molding quality is poor, difficult to fully meet the requirements of stability, it is necessary to adopt the technology some measures to improve an effective measures and adding proper amount of cement stabilized silty soil is in unfavorable factors.
