Falling Weight Deflectometer Relative Calibration Analysis
Non-destructive deflection testing with Falling Weight Deflectometers (FWDs) is a critical element of the pavement monitoring effort for the Long-Term Pavement Performance (LTPP) test sections of the Strategic Highway Research Program. Data obtained through this testing serves as the primary mechanism for assessing structural conditions within each LTPP test section. For the LTPP deflection data to serve its intended purpose, the deflection testing must be conducted consistently, and with accurately calibrated FWDs. This report documents the FWDCAL software, which was developed to help ensure that the latter need is met. SHRP FWD testing procedures require that the FWDs used be calibrated on a regular basis. One aspect of this requirement is monthly relative calibration of the FWD deflection measurement system. This process involves stacking the deflection sensors, one above another, in a special stand, so that all will simultaneously measure the deflection of the pavement at the same point.
