Background for Development of Mechanistic Based Design Procedure for Jointed Concrete Pavements

摘要

Background information needed for the development of a mechanistic based design procedure for jointed concrete pavements was developed and reviewed. Mechanistic models available to analyze jointed pavement systems were reviewed and evaluated. Responses of pavement systems to load and climatic factors were evaluated, and correlated to performance of pavements in service. Based on these correlations, a fatigue based thickness design procedure was proposed to determine the thickness of jointed concrete pavements. Instrumented pavement sections were constructed and tested in both southern and northern Illinois to validate the mathematical models used in the proposed design procedure.
