摘　　要：通过对兰 (考 )许 (昌 )高速公路粉质砂性土路基试验路段进行压实度、沉降量及横向位移等检测分析 ,介绍冲击压实技术在粉质砂性土路基碾压中的应用情况。The powder sand character sub grade is a sort of the badness soil in highway construction. So as to adopt impact compaction techniques in Lankao-Xuch ang free way powder sand character sub grade strong impact compaction, get across the ins pection and analyses compaction, sedimentation and landscape orientation displac ement. It is make know that the impact compaction techniques in freeway the powd er sand character sub grade strong is viable. The paper is mostly expatiated on impact compacter applications on compaction of the from Lankao to Xuchang freewa y sub grade mend strong.
