Correlation of Rut Depths Measured by the Profilers of LTRC and DOTD PMS

The objective of this study is to develop a correlation of rut depths measured with Louisiana Transportation Research Center (LTRC)’s profiler with a 5-point laser system and Department of Transportation and Development (DOTD) pavement management system (PMS)’s profiler with a scanning laser system. A Standard Operating Procedure (SOP) of pavement rutting data collection, compilation, and delivery by LTRC will be developed so that DOTD pavement engineers can use LTRC data together with PMS data to evaluate the pavement performance and conduct/support pavement management activities.
