摘　　要：风积沙作为沙地区填筑路基材料,其路用性能与一般填土相比有其特殊性.依托内蒙古科尔沁沙地公路实体工程,通过室内试验,在分析科尔沁沙地区风积沙基本物理性质的基础上,研究风积沙的路用性能指标回弹模量、CBR受含水率、干密度、压实度影响规律,对该地区同类工程建设具有一定的参考意义.Pavement performance of aeolian sand as subgrade filler in the sandy land has its particularity which is different from common filler.Based on the analysis of the basic physical properties of aeolian sand by laboratory test,the influence laws of road performance indexes of the aeolian sand which are influenced by moisture content,dry density,degree of compaction such as resilient modulus and California Bearing Ratio（CBR）are studied according to actual road engineering in Horqin Sandy Land of Inner Mongolia.There are some certain reference values for the similar engineering construction in this area.

关 键 词：风积沙 回弹模量 CBR 含水率 干密度
