LI Zhixiang ①HU Ruilin ①XIONG Yesheng ②HU Xiaorong ③SONG Jihong ② (①Insititute of Geolody and Geophysics, Chinese Academia of Sciences, Beijing 100029) (②Hubei Province Xiaoxiang Expressway Construction Headquarters,Suizhou 410014) (③China Raiway 4 Bureau Group Ltd.,Xiangfan 441004)  
This paper presents experimental shearing and swelling results of the modified expansive clay with different water contents and lime (cement) content. The influence of the water content and the lime (cement) content on the shearing strength and swelling capacity are evaluated according to the experimental results. The optimal water content and lime content are then obtained. The authors also provide guidelines for modification of expansive clay.
