Considerable labor savings (100% reduction) and time savings (nearly 35% reduction) were gained. In the process of local calibration, automation was used during software runs and data compiling to minimize human interaction with the computer. The NCAT database was developed with research-grade detail and accuracy and was locally-based regarding the information of materials, traffic, and climate, and field performance. The National Center for Asphalt Technology (NCAT), equipped with a full-scale accelerated pavement Test Track and asphalt materials laboratory, supported this study on evaluation, local calibration, and validation of the rutting, bottom-up fatigue cracking, and IRI models. These models may not apply to local pavement designs due to insufficient adequacy. The performance prediction models in the software were only calibrated based on a national database of pavement sections in the U.S. The AASHTOWareTM Pavement ME Design software was adopted by the American Association of State Highway and Transportation Officials (AASHTO) for structural pavement designs.
