摘要：

Based on the improved trial test of a construction section of expansive soil subgrade filling in Small Crow first class road in Yi Chang, a comparative analysis about the improvement on the swell-shrink performance of expansive soil test sample by adding lime, cement, fly ash, weathered sand is made. From the applicability and economic perspective, weathered sand improvement with the best effect. The best construction mixing sand ratio for medium and strong expansive soil is determined as10%, the expansive soil after improved treatment can be used as the first class road subgrade filling.
