The Nebraska Department of Roads (NDOR) conducts annual examinations of the Nebraska’s interstate and federal high-way pavements. During these examinations, numerous indicators of pavement quality are measured directly or are com-piled from parameters recorded by a vehicle passing over the pavement section. Parameters are documented and analyzed for each one-tenth mile segment. A number of pavement sections where innovative features have been incorporated were selected by the NDOR for comparison to nearby conventional pavement sections. This study used data recorded by the NDOR as well as field observations to develop a comparison between two pavement sections, one with innovative fea-tures incorporated and a second of more conventional design . Pavement quality indicators measured and compared included Nebraska Serviceability Index, International Roughness Index, Present Serviceability Index, cracking index, rutting, faulting, and longitudinal and transverse cracking. Pavement sections where innovative features were incorporated generally performed better than pavement sections where only more conventional features were used.
