Alternative Validation Practice of an Automated Faulting Measurement Method

Abstract

Several states have adopted profiler-based systems for automatic measurement of faulting in jointed concrete pavements. However, little published work exists that documents the validation process for these automated faulting systems. An alternative practice for making an initial assessment of a newly developed automated faulting method was documented. Findings from this experiment showed that a high-speed inertial profiler used in conjunction with a faulting reference device provides a practical validation method under controlled conditions. Furthermore, the algorithm that controls the automated faulting measurement method provides reliable and highly repeatable faulting results. The test equipment used in the experiment, as well as the data collection process, the analysis, the subsequent findings and recommendations, are documented.
