Abstract:A number of states have adopted profiler based systems to automatically measure faulting,
in jointed concrete pavements. However, little published work exists which documents the
validation process used for such automated faulting systems. This paper documents an alternative
practice for making an initial assessment of a newly developed automated faulting method.
Findings from this experiment show 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 which controls the automated faulting measurement method provides
reliable, highly repeatable and reproducible faulting results. This paper also documents the test
equipment used in the experiment as well as the data collection efforts, the data analysis and
subsequent findings and recommendations
