Book excerpt: In this study, roughness of 17 pavement sections, built between 1998 and 2001 were analyzed. These sections were constructed over different subgrade and base types, and different asphalt binder aggregates were used. Annual roughness data was collected from the Pavement Management Information System database of the Kansas Department of Transportation. In addition, five new sections, built over the last three years, were also monitored. Roughness data on these sections were collected periodically. International Roughness Index (IRI) was used as the roughness statistic for analyzing both types of sections.
