This report documents the development of the Long-Term Pavement Performance (LTPP) automated faulting measurement (AFM) algorithm to identify transverse joint locations on jointed plain concrete pavements and compute faulting at these locations using the profile data collected by LTPP high-speed inertial profilers. The LTPP AFM algorithm is intended to replace traditional manual faulting surveys that entail traffic control and significant survey time from State departments of transportation and highway agencies. The software program developed based on this algorithm will serve as an automated tool for highway engineers to significantly increase their productivity when detecting transverse joint locations with acceptable accuracy.
