Abstract: In order to effectively utilize the waste wet soils with high liquid limit in PanXin Highway Project, this paper presents the experimental study results of the mixture of wet soils and various cementitious materials. These experimental studies included the grain size distribution analysis of the mixtures; Atterberg Limits, Proctor Test as well as California Bearing Ratio tests. The optimum cementitious material contents under different degrees of compaction are obtained and their construction parameters are also studied. Under the optimum mix content, the moisture content, degree of compaction, compaction energy relationships that can reaching the balance between the environmental stability and the mixture strength are obtained.

Key words: High Liquid Limit Soils, Soil Modifications, Experimental Studies
