To increase accuracy and minimize exposure to traffic, the Georgia Fault Meter was used. This handheld instrument is placed across a joint and displays the faulting measurement. It is more accurate than listening to traffic passing over the joint. However, it is still labor intensive because each joint must be measured and manually recorded.
There may be a way to measure faulting with the use of the road profiler. Having an automated method to collect this distress would place a much greater level of confidence in the faulting rating. In the future, it would allow the distress surveyors to concentrate on the other concrete distresses.
Roadware®, whose ARAN™ profiler system is used by SDDOT, has produced faulting software to be used along with its profile software. The software must be purchased from Roadware for evaluation purposes. If the software is inadequate, software may have to be developed to meet the Departments needs.
