Abstract:  With the development of China's highway structure in desert area,we often meet the problems of using different clay-content aeolian sand to build roadbed.However,if the different mud-content aeolian sand can be used as the stuffing of roadbed and what about the roadbed's effect They relate to the strength properties of the different mud-content aeolian sand.In order to ascertain right the stuffing of roadbed of the mud-content aeolian sand and estimate exactly the strength properties of the different mud-content aeolian sand,this paper studies the strength properties experiment(direct-shear experiment,rebound modulus experiment,CBR experiment)of different mud-content aeolian sad through datum research,project practice,laboratory experiment and theory analysis,and combining the actual engineering.The experiment results show that strength properties is good,and is adapted to do the stuffing of roadbed when the mud-conten of aeolian sand is about 15%,and these have instruction and ecnomic
