摘要：	One of the primary objectives of the Strategic Highway Research Program Long Term Pavement Performance (SHRP-LTPP) studies is to improve the ability of highway engineers to design new and overlaid pavement structures. The specific analyses discussed in this report were aimed at evaluation of the American Association of State Highway and Transportation Officials (AASHTO) pavement design equations (for both new and overlaid pavements). Initial analyses confirm that although improvements have been made to the AASHTO design equations over the years, the equations still do not fully explain data from North American pavements. Recommendations for the improvement of the design equations are provided; however, the highway community at large supports replacing the limited equations with a comprehensive design system that considers all distress types.
