The research project was conducted to evaluate the performance of an inexpensive non-contact roughness measuring device, Roughness Surveyor, as well as the potential use of this device as a calibration reference for Response-Type Road Roughness Measuring (RTRRM) systems. A correlation was also conducted between RTRRM systems from three different States (Georgia, Florida, and Minnesota) against the Roughness Surveyor, the inertial profilometer owned by the Ohio DOT, and the profilometer designed and operated by the South Dakota DOT. A total of sixteen test sites were selected for the correlation and calibration study with a total of 52 individual test sections encompassing a variety of roughness levels and pavement surface types.
