Testing Program for the Falling-Weight Deflectometer
NYSDOT has purchased a non-destructive testing device (the falling-weight deflectometer or FWD) manufactured by Dynatest, Inc., to improve New York pavement design practice. Pavement deflection measured with the FWD can be used to assess pavement structural condition by evaluating parameters of in-situ materials. To serve its intended purpose, however, deflection testing must be conducted consistently, with an accurately calibrated FWD. This report documents procedures followed in 1994 deflection testing it at ten selected sites--seven in NYSDOT Region 1, two in Region 6, and one in Region 9. It describes the testing program, giving guidelines for testing at each site and for field quality assurance, data acquisition, and calibration. In addition to deflection testing, pavements were cored and sampled to provide specimens for laboratory characterization of paving materials, and to verify pavement layer thicknesses. Based on this experience in field testing and data analysis, further guidelines are being developed for future FWD testing.
