AASHTO R 32-11

This standard practice covers the annual calibration of the load cell and the deflection sensors andmonthly relative calibration of the deflection sensors of a falling weight deflectometer (FWD) or aheavy weight deflectometer (HWD). It is used to establish calibration factors for correcting FWDand HWD measurements.

For this practice, the term FWD also refers to an HWD unless otherwise noted.
