Abstract:This manual is intended for use in collection of Falling Weight Deflectometer (FWD) data for the Long-Term Pavement Performance (LTPP) program. As such, it contains background information
on FWD equipment and the general role of FWD testing within LTPP as well as a set of field
operations guidelines for the data collection process. This is the fourth major version of the LTPP Manual for Falling Weight Deflectometer Measurements. The first two were developed under the auspices of the Strategic Highway Research Program; the last two were developed under contract to the Federal Highway Administration. The revisions to this manual reflect the changing data needs of LTPP as well as changes in FWD equipment. This manual provides background information and field operations guidelines for the collection of Falling Weight Deflectometer (FWD) data on Long Term Pavement Performance (LTPP) test sections. It includes equipment setup, equipment calibration, test locations, and test procedures.
