The days in which we can significantly advance the science of pavement engineering through purely empirical approaches are over. Instead, we must turn to mechanistically based analyses, which seek to explain the mechanisms associated with pavement deterioration. This fact is reflected in the requirement that the 2002 Guide for Design of New and Rehabilitated Pavement Structures (2002 Guide), currently under development through the National Cooperative Highway Research Program, be based on mechanistic concepts.
This report is the first of a two-volume series documenting the first-ever application of Long Term Pavement Performance (LTPP) data to the evaluation of mechanistically based performance prediction procedures for flexible pavements. Volume II: Final Report—Appendices is available only through the National Technical Information Service (NTIS).
This report will be of benefit to those interested in the development of mechanistically based performance prediction and design procedures for flexible pavements. It will be of particular interest to those involved in the development of the 2002 Guide.
