Description:

The Road Profilometer Meeting was held in Ann Arbor in September 1984. In this meeting, 11 agencies used their profilometer equipment to provide measures over 27 test sites. Overall, 13 independent instruments were used, including static rod and level measures on 10 of the sites. Analyses; of the profiles obtained in the experiment were used to determine and compare some of the performance characteristics of profilometers in use today, The profiles from each system were processed to yield quartercar roughness, RMSVA roughness, power spectral density functions, and waveband indices. Plots of filtered profiles were also compared. These results were used to determine the performance limits of the profilometers, in terms of operating speed, surface type, and roughness level. Most of the profilometers were demonstrated to measure valid profiles over a full range of pavement roughness, with varying degrees of accuracy that depend on the particular profilometer and the analysis used. Some of the profiles submitted were not valid, indicating that better datachecking methods need to be adopted.
