4 1.1 Problem Statement State highway agencies monitor pavement roughness to assess road network condition and for other purposes, such as assessing construction quality and optimizing investments in preservation, rehabilitation, and reconstruction. States are also required to report the International Roughness Index (IRI)

5 Second, with the application of proper measurement requirements, profiles contain the information needed to diagnose the sources of roughness that degrade ride quality and other serviceability factors. In addition to the calculation of a summary roughness index, an important application of profiles is to identify localized roughness and quantify its severity.
