Abstract
The development and evaluations are described of prorut, an inertial profiling system which can be used to measure and record various roadway characteristics, including the longituudinal profiles, rutting, and roughness levels of the two wheel tracks. Laser sensors and accelerometers are used to obtain the profile measurements in eachwheel track. An ibm personal computer controls system operation andprocesses the data. The system was then evaluated by the states (georgia, pennsylvania, indiana), and the results are reported. The field tests demonstrated that prorut provided useful pavement profile information and that its output could be correlated to several response-type measurement systems.
