Flooded Backfill

Location:  Frisco 2

Speaker:  Wes Musgrove – IowaDOT

Presentation Description
When backfilling and compaction by flooding is required, backfill may be placed in lifts up to 2 feet thick. Place backfill simultaneously on both sides of culvert. Determine if pipe culverts need to be restrained and take appropriate actions to prevent floating of culverts during backfilling, flooding, and compaction. This session will cover Iowa DOT’s path to the use of flooded backfill. From recognizing pavement degradation issues at culvert crossings, to evaluation of the cause, to the results of the solution. Flooded backfill has provided benefits surpassing the expectation for Iowa DOT.
