• Description:
  Three methods were tested in full-scale highway construction for their effectiveness at reducing the bump at the end of the bridge: expanded polystyrene, flowfill, and structural backfill. Vertical settlement, lateral movement, and soil pressure behind the abutments were monitored during and after construction. Based on finding of this study, flowfill material has the best performance among the three in controlling lateral pressure and movement behind the bridge abutments. Further, flowfill shows the least post-construction compression and provides a better ride than the other two materials tested.
