Mechanistic Evaluation of Test Data From LTPP Jointed Concrete Pavement Test Sections

PDF Version (4.58 MB)

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 documents the application of Long Term Pavement Performance (LTPP) data to the evaluation of mechanistically-based performance prediction procedures for jointed concrete pavements. It will be of benefit to those interested in the development of mechanistically-based performance prediction and design procedures for jointed concrete pavements. It will be of particular interest to those involved in the development of the 2002 Guide.
