Abstract:Preliminary results from the Ohio Strategic Highway Research Program (SHRP) Test Road point to the falling Weight Deflectometer (FWD) as being an effective tool for monitoring the stiffness of individual layers in the pavement structure during construction and, thereby, providing the opportunity for repairing areas of reduced support prior to completion of the pavement. By eliminating these potential problems before the pavement is opened to traffic, performance will be greatly enhanced. Variability in subgrade and base stiffness is a major contributor to premature distress on asphalt concrete pavements, as evidenced by localized failures where heavy traffic loads either punch through the pavement or cause severe wheel path rutting and cracking associated with poor support.
