• Abstract:
  Wet, unstable subgrade soil conditions are often encountered during new or reconstruction projects. The problems are often unidentified during plan development stage. Once the existing pavement is removed, the unstable subgrade must be modified or replaced to provide an acceptable surface for pavement construction. This often results in change orders for the additional work, causing significant cost overruns. ; ODOT has recently developed guidelines for subgrade treatments to be used during plan development and construction. This study evaluates these guidelines by comparing them with existing guidelines developed elsewhere and validating them through comparison of the actual treatment methods and quantities used with those suggested by the guidelines.
