Effect of Dynamic Compaction on Red Sand Soil Filling Embankment

Abstract: The scheme and implement of dynamic compaction on red sand soil embankment, Ying(tan)-Rui(jin) expressway, is introduced in this study. The settlement of the subgrade in the field was observed. The density and the water content of it were tested. Then bearing capacity of the subgrade was detected by PFWD. All the work done is to analyze the effect of dynamic compaction on the red sand soil roadbed. It shows that the water content decreases while the strength increases with compaction. That is, the embankment is compacted effectively by dynamic compaction.
