摘要：	The main goals of this study were to evaluate the rut depth measurement collection techniques used by ODOT and to verify data gathered using the automated laser rut measurement system. To meet these goals, the following objectives were devised and met: (1) Conduct tests on a section of rutted pavement at one or more locations using the LRMS, straight edges, and profilometer (Evaluate the LRMS data for precision, accuracy, and repeatability using the S&G method and Ohio Research Institute for Transportation and the Environment (ORITE) profilometer as references, Examine the potential effect of straight edge length on the accuracy of S&G measurements to determine whether the 4ft straight edge used by ODOT is adequate); (2) Develop a method for extracting rutting distress scores from the LRMS data to be used with the ODOT pavement condition rating system; (3) Recommend other parameters (maximum, minimum, etc.) that may be suggested by the data for the use and interpretation of INO rut depth measurements.
