Publication Details

Investigation of Increase in Roughness Due to Environmental Factors in Flexible Pavements Using Profile Data From Long-Term Pavement Performance Specific Pavement Studies 1 Experiment Research/Reference: useful for researchers doing further work in the pavement area as well as those developing improved testing and design procedures. Includes documents of historical value.

Primary Topic: Pavement Evaluation

Description: The goal of this study was to evaluate the changes in roughness as measured by the International Roughness Index (IRI) along the center of the lane at Specific Pavement Studies 1 (structural factors for flexible pavement) sections over time and identify environmental and subgrade parameters that contribute to the increase in roughness.
