| 摘要： | This report characterizes the longitudinal profiles of eleven pavement sections within the Arizona Specific Pavement Studies 5 (SPS-5) project throughout their service life. The pavement associated with this project was rehabilitated and monitored as part of the Long-Term Pavement Performance Study. Road profile measurements were collected on the in-service pavement before rehabilitation was performed and twelve times over the sixteen years afterward. This study analyzed the profiles in detail by calculating their roughness values, examining the spatial distribution of roughness within them, viewing them with post-processing filters, and examining their spectral properties. These analyses provided details about the roughness characteristics of the road and provided a basis for quantifying and explaining the changes in roughness with time, as well as linking profile properties to each section's maintenance history and observations of surface distress. / NOTE: Final rept.
