• Abstract:
  The purpose of this study is to determine through statistical analysis if the dynamic cone penetrometer (DCP) can be used as a reliable method of quality assurance to evaluate in-situ resilient modulus (MR) of a reclaimed stabilized base (RSB) in full depth reclamation (FDR) projects. DCP data collected by contractors from the RSB layer at the time of placement and compaction from five separate full-depth reclamation projects with RSBs was provided for this analysis. For comparison to the DCP data, MR determined from falling weight deflectometer (FWD) testing was obtained on three of these projects about 10 to 18 months following construction.
