• Abstract:
  Pavement rutting can be an indicator that a section of roadway is in need of repair or replacement. It can also become ; a hazard to drivers, causing loss of control or hydroplaning when water accumulates. To better monitor pavement ; conditions throughout the state, the Ohio Department of Transportation (ODOT) purchased two road profilers with ; INO Laser Rut Measurement Systems (LRMS). The vehicle mounted systems provide ODOT pavement condition ; raters with a faster and safer method for evaluating pavement conditions. This study was intended to evaluate the ; accuracy, precision, and repeatability of the LRMS system and determine the correlation between manually collected ; data and data collected using the LRMS. The system’s performance was evaluated by collecting rut measurements over ; two sections of pavement using the LRMS, the straight edge method, and a mechanical profiling system developed by ; the Ohio Research Institute for Transportation and the Environment (ORITE) and comparing results. The study ; showed that the LRMS produces accurate and repeatable results that are similar to those produced with a straight edge ; or profilometer. Minor adjustments to the Pavement Condition Rating (PCR) system are needed, however, to ensure ; that scores properly represent the condition of the pavement. A range of 5-25% is recommended for the “occasional” ; extent classification when the LRMS is used.
