Lime-treated expansive soils roadbed construction

With a shallow analysis on the principium of lime-treated expansive soils and the engineering properties,it introduces the construction technology and control points of lime-treated expansive soils.Based on referring to common subgrade construction procedure and combining with lime-mixing technology,it summarizes construction technology of three stages,six sections,ten procedures and control points in construction process,and accumulates the construction experience of lime-treated expansive soils roadbed.
