With the increase in rutting seen in Texas over the last few years, a reliable rut measuring system has been needed. This report provides results of research performed for the Texas Department of Transportation which would assist in developing a more reliable rut measuring system. A phototype rut bar constructed in the Transportation Instrumentation Laboratory at University of Texas at Arlington with the five acoustic sensors, was used for developing and/or implementing the various rut measurement algorithms. In order to collect accurate rut data, which includes rutting generated by trucks, extensions outside the vehicle body are required so that the outer wheel paths can be measured. Laser light has been used by some data collection equipment to alleviate this problem. However, the lasers used are very expensive compared to the ultrasonic sensors and could be destroyed in an accident. When a suitable system was not found, a laser based measuring system was developed and investigated. This system is described in the report and could possibly be used as an alternative to the more expensive higher resolution systems.
