高速公路含砂低液限粘土路基施工

On construction of sand low liquid limit clay roadbed on expressways

以靖安高速公路含砂低液限粘土路基施工工程为例,介绍了该路段路基的压实标准和最大干密度的确定方法,总结了机械的选择与组合要点,并对路基的压实工艺作了具体阐述,为今后西北及沙漠地区高等级公路的修筑提供了参考依据。

Taking the project of sand low liquid limit clay roadbed on Jingbian-Ansai Expressway as the example,the paper introduces the com-pact standard of the roadbed and the identifying methods for the maximum dry density,sums up the mechanic selection and combination points, and illustrates the compact craft of the roadbed,so as to provide some reference for the high-grade road in northwest and deserts of China.
