Abstract:

This project was initiated to investigate the profile measuring capability of the Siometer or (Walker self-calibrating process) so that it might be used for various profile measuring applications. Since the Siometer is capable of providing pavement profile estimates, it was desired to determine how closely these estimates were to actual profile, or to profile measurements made by the Surface Dynamics Profilometer (SDP) owned by the State. For the study, profile data from the Siometer was compared to that from the SDP for the same sections. From the results of the study the self- calibrating process does a good job of measuring the longer profile wavelengths (about eight feet and greater). The shorter wavelengths are somewhat attenuated. The Siometer has been modified to implement the acceleration only, and South Dakota processes for measuring profiles and rutting. The acoustic sensor provides better estimates of the shorter wavelengths which could also make the unit more suitable for profile measurements.
