摘　　要：在公路建设中经常遇到把旧路改建成一、二级公路的情况,针对河北省地区的土质情况,不能直接在零填挖土基上做路面结构层,需对不同类型的土基采取相应处理措施。文中介绍了3种类型土基下路基处理方案的选定过程,并根据不同的试验方法和依据提出了具体的处理方案。In the construction of the highways, there are often the conditions of rebuilding the old roads into Class 1 and Class 2 highways. To counter the soil condition of Hebei Province, the structural course of the pavement can not be directly constructed on the zero filling and excavating ground. The relative treatment measures are taken for the different kinds of the soil ground. The article introduces the selecting processes of the subgrade treatment schemes under three kinds of soil grounds, and puts forward the detail treatment schemes on the different test methods and bases.
