The current U.S. Highway Performance Monitoring System (HPMS) requires state highway agencies (SHA) to report to the U.S. Federal Highway Administration (FHWA) a set of pavement-condition data, which includes faulting data on jointed concrete pavements, among other data items. To address this pressing need for an automated fault-measurement method based on pavement profile data to reduce the risk associated with manual faulting measurements, the authors developed an automated faulting measurements (AFM) module in the profile viewing and analysis tool (ProVAL), to allow practical application of this method for state department of transportation (DOT) users. This paper describes the development of the AFM algorithm (including joint finding and joint fault computation), the associated field validation program, recommended profile measurement methodology, and usage/limitation of the AFM tool on the ProVAL platform. Through the peer reviews and field validation efforts, the AFM is shown to be an effective tool for implementation of automated fault measurements. Therefore, the AFM is served as the basis for AASHTO R 36–12 “Standard Practice for Estimating Faulting of Concrete Pavements.”
