Long-Term Pavement Performance Program Manual for Falling Weight Deflectometer Measurements

Research/Reference: useful for researchers doing further work in the pavement area as well as those developing improved testing and design procedures. Includes documents of historical value.

Primary Topic: Pavement Issues

Description: 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.
