Roughness Progression on KDOT Asphalt Pavements
Pavement smoothness is a major factor affecting performance. Since the introduction of the Superpave system in Kansas, bonus payment for asphalt pavement construction has increased significantly, indicating that these pavements are smoother initially. However, roughness (or lack of smoothness) progression on these pavements is yet to be determined. In this study, roughness of 17 pavement sections, built between 1998 and 2001, was analyzed. These sections were constructed over different subgrade and base types, and different asphalt binder grades 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 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.
