Book Description
"This project was conducted to describe and evaluate the South Dakota Road Profiler for Demonstration Project 72, 'Evaluation of Equipment for Measuring Pavement Roughness and Rut Depth'. The Road Profiler's profile and rut depth performance were evaluated by comparisons to surveys taken with rod and level and the E.W. Face 'Dipstick'. For each of ten sites, the Road Profiler's measurements at 25, 40 and 55 miles per hour were compared to the manual surveys. Spectral analysis and the International Roughness Index were used to compare profile data, while plots and averages were used to compare rut depth data. The rut Profiler's profile and rut depth measurements correlated well with Dipstick measurements. Minor sensitivity to pavement texture was observed. No operational difficulties were encountered"--Technical report documentation page.

Book Description
This project evaluates the rut-depth-measurement capability of a three-sensor South Dakota Road Profiler (SDRP), which was built in-house in 1990. The study is divided into six components, which include a statistical comparison of mean-rut-depth measurements obtained with the SDRP, a Dipstick Autoread Profiler and 6-ft straightedges; evaluations of repeatability and vehicle-driver-positioning ability; and, studies of the dependency of SDRP-measured rut depth on vehicle speed, acceleration, deceleration and vehicle lateral position relative to the actual rut location.
