Based on the laboratory tests, the influences of two subgrade compaction controlling index to the subgrade stability were compared, and a conclusion was obtained that it is feasible to control the quality of subgrae compaction by air rate.

• 摘要从室内试验出发，对比了国内外两种路基压实控制指标对路基稳定性的影响，得出了采用空气率控制路基压实质量的可行性结论。
