The primary objective of this study was to identify data errors or anomalies in the Long-Term Pavement Performance (LTPP) load-deflection database that were not identified during routine screening required to reach level E. Routine screening applies more general procedures, such as broad range checks, to the data. The intent of this study was to review the level E deflection data and ancillary information, looking for data discrepancies and errors that routing screening may not have identified. The overall objective of the postscreening final data check was to assure that good quality load-deflection and ancillary data are available for researchers and highway engineers.
