Paper introduces the characteristics of expansive soil and its classification scheme, reviews the treatment method of expansive soil and expansive soil sub-grade. Lime, cement and fly ash are useful admixtures for expansive soil treatments, their relevant properties are summarized and analyzed. And a reasonable structure of expansive soil sub-grade is recommended. According to the characteristics of expansive soil and the research’ s status, some development trends are putted forward.
