皖北地区稳定粉砂土由于土质中的细粒较多，不可直接用作公路路基的基层填筑材料。为此，要研究该地区稳定粉砂土的压实特性，分析影响压实的因素和压实规律，并提出适宜此类土的压实工艺、施工控制指标，并将其运用在各等级公路施工中。

Because the stabilized sand and silt in Northern Anhui has many fractions, it can not be directly used as fil ing material of the subgrade base of highway. Therefore, we need to study the compaction characteristics of the stabilized sand and silt in the region, to analyze the factors influencing the compaction and the compaction law, and to put forward co-mpaction process appropriate for such soil and the correspo-nding construction control index and its application in grades of road construction.
