【Abstract】 Based on the actual situation of the subgrade construction site of Chengwei expressway, the collapsible loess is improved with cement and used for roadbed filling to ensure good compaction quality. At the same time, the construction equipment is reasonably arranged and the mechanical combination is optimized. Combined with indoor test and on-site test, the parameters are collected and the construction experience is summarized, It has done a good guiding role for the cement soil construction in the collapsible loess area in the future.
