CONSISTENCY OF ROUGHNESS AND RUT DEPTH MEASUREMENT COLLECTED WITH 11 SOUTH DAKOTA ROAD PROFILERS

Pavement roughness has long been recognized as a primary indicator of pavement performance. To provide accurate and reliable roughness measurements, the South Dakota Department of Transportation (SDDOT) designed and constructed a profilometer system in 1982. This system was later improved and enhanced by adding more sensors for rut measurements. The increased interest in the road profiler resulted in the establishment in 1989 of the South Dakota Road Profiler User's Group (SDRPUG). During the Third Annual SDRPUG meeting in Minnesota in 1991, international roughness index and rut depth data were collected with 11 road profilers on 4 different pavement surfaces. These selected pavement types were concrete, bituminous, concrete-bituminous over concrete, and bituminous over concrete. Each road profiler was run three time over each test section. The collected data were then reduced and analyzed statistically. The main objective of the statistical analysis was to determine whether the differences in roughness and rut measurements obtained with the 11 road profilers were statistically significant. The experiment and the statistical analysis are described in detail. In addition, specific recommendations are provided for the need to establish calibration procedures to ensure consistency in roughness and rut depth measurements obtained nationwide.
