Plate Load Test Applied to Detect Bearing Capacity of the Miscellaneous Fill Subgrade Reinforced by the Dynamic Compaction

Abstract

In view of the dynamic compaction method to reinforce the miscellaneous fill subgrade plate load test, the consolidation of the miscellaneous fill characteristic value of subgrade bearing capacity is between 160~326 KPa, and foundation coefficient K30 value is between 122~229 MPa/m. The degree of miscellaneous fill reinforced roadbed compaction is located in between 94.8%~ 99.0%,which is detected through the sand filling method . Plate load test can be used as one of the evaluation index of highway roadbed performance.
