摘要: |
Nondestructive deflection testing with Falling Weight Deflectometers (FWDs) is a critical element of the pavement monitoring effort for the Long-Term Pavement Performance (LTPP) testing of the Strategic Highway Research Program. The deflection testing must be conducted consistently and with accurately calibrated FWDs. This is a report of the FWDCAL software, which was developed to help ensure that. One aspect of this is the monthly relative calibration of the FWD deflection measurement system. The details are described of how a data set is obtained which can be analyzed to (1) determine a multiplier for each sensor; and statistically partition the measurement errors in the data to the major sources of error, as a check on the acceptability of the calibration data. The FWDCAL software is described which was developed to perform these analyses. |
