| Abstract: | Based on the impact rolling technology having good compaction performance,this paper proposes application method and key technology when it is used in fine-grained soil subgrade.The technical parameters such as filler selection,thickness of layers,stamping method and times as well as construction method and process are determined;and the quality inspection is improved.The results show that the fined-grained soil subgrade using this technology has satisfied the compactness and other technical indexes,shortened construction period,and reduced cost. |
