| Abstract | The American Association of State Highway and Transportation Official's (AASHTO) Guide for the Design of Pavement Structures is widely used in the design of new and rehabilitated highway pavements. However, the current Design Guide, published in 1993, is widely recognized as being inadequate for the design challenges currently faced by highway agencies because it relies on empirically based procedures founded on test data that are not representative of current pavement design conditions. The 1993 Design Guide does not offer the best available design procedures. For this reason, the National Cooperative Highway Research Program (NCHRP) has undertaken Project 1-37A, "Development of the 2002 Guide for the Design of New and Rehabilitated Pavement Structures". This pamphlet discusses the reasons that a new Design Guide is possible, and lists its benefits. It describes the Long Term Pavement Performance (LTPP) program and discusses how the LTPP data address the current Design Guide's limitations. Included are discussions of traffic loadings, LTPP test sections, and data on rehabilitation, climate, subgrade materials, base materials, vehicle fleet, drainage and distress. The pamphlet explores the LTPP and procedures that will be used as inputs for evaluation. It discusses the LTPP data which will be used for calibration and validation. Finally, it describes the role of LTPP data in the future enhancement of the 2002 Design Guide. Special Pavement Sections (SPS), and the useful data they will generate, are described. |
