The Colorado Department of Transportation (CDOT) spends more than 30 percent of its annual construction and maintenance budget on pavements, so pavements need to be properly designed using an analytical process with accurate design inputs. A pavement design needs to be performed during the early phase of project development to estimate and establish the project cost. The performance life of the initial pavement design and associated rehabilitations greatly impact the life cycle cost analysis (LCCA) used to determine the most cost-effective final pavement design. Currently, due to lack of actual data, an assumption of the expected life of an asphalt pavement is often being made. Thus, a precise initial pavement life span is essential for developing a reliable forecasting model and an accurate LCCA. This study evaluated the performance of four roadway functional classes utilized by CDOT: interstates, principal arterials, minor arterials, and major collectors. Performance was evaluated with respect to smoothness, permanent deformation, fatigue cracking, transverse cracking, and longitudinal cracking.
