Application of Impact Compaction Technology in Subgrade of Expressway

Chen Yan-xin

Abstract

Impact compaction method can reduce the settlement of subgrade after construction,im-prove the integral strength of subgrade soil and effectively prevent the forepart breakage of pavements caused by the quality problems of subgrade soil. The result of impact compaction tests is that the finitude of impact compaction is 18 times,and the effective depth of impact compaction is 1.5 meters.
