| Abstract: | Impact compaction method can reduce the settlement of subgrade after construction, improve 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. |
