Utilization Of Light Detection And Ranging For Quality Control And Quality Assurance Of Pavement Grades, Brad W. Rister, Levi Mcintosh, Gabriel B. Dadi, Ruigang Yang, Eileen Grady

Kentucky Transportation Center Research Report

Light Detection and Ranging (Lidar) technology is a useful tool that can assist transportation agencies during the design, construction, and maintenance phases of transportation projects. To demonstrate the utility of Lidar, this report discusses how Lidar data can be used while performing quality control and quality assurance (QC/QA) of pavement grades along road segments where safety concerns have been identified (e.g., increased crash rates due to water ponding on the roadway). Researchers modeled surface runoff using Lidar data for several roadways that had experienced significant crash increases during wet-weather events. Based on this modeling, the Kentucky Transportation Cabinet (KYTC) undertook …
