The Texas Department of Transportation (TxDOT) has been using a five-sensor rut bar system that uses measurements made with ultrasonic sensor technology to automatically collect pavement rutting for Pavement Management Information System (PMIS) purposes. A number of problems have occurred while using the acoustic sensors for these measurements. This report discusses the results from Project 0-1782 between the Texas Department of Transportation and The University of Texas at Arlington, titled Development of a Real-Time Transverse Pavement Profile Measurement System. The project was initiated to investigate the uses of scanning laser technology for measurement of rut that would alleviate some of the problems and limitations of the acoustic sensor systems.
