| Abstract: | Based on experimental study of Bengming highway expansive soils bankment with the lime- treated expansive soils, systematic study of compaction character of the lime-treated expansive soils is conducted. Considered the compaction character and mechanics function of expansive soils, construction and treatment of bankment packing are analyzed and demonstrated. Engineering experiences show that lime- treated expansive soil of low dose is a flexible and efficient treatment method. |
