State highway agencies (SHAs) in New England have an ongoing interest in providing the public with smoother rides. As an incentive to contractors, some SHAs include a bonus and penalty clause for new construction based on profile measurements and smoothness indices. These states are considering the use of high-speed profilers for profile measurements and quality control/quality assurance implementation. Therefore, an assessment of the accuracy and repeatability of these devices is essential. A comparative study of high-speed profilers owned by the New England SHAs was conducted in Worcester, Massachusetts. Two sites were profiled using the dipstick and the high-speed profiling devices. Statistical analysis of International Roughness Index measurements were used for evaluation of precision and bias, profiler speed, and sensor type. The repeatability for the profilers was good, especially for combined wheel paths (standard deviation between 0.016 and 0.079 m/km). The accuracy for the profilers varied depending on profiler type.
