Non destructive evaluation of rigid pavements using road rater deflections

The aim of this paper is to summarize and document research and developments relating to the use and application of dynamic deflection measurements (specifically Road Rater deflections) for evaluation of rigid pavements in Kentucky. Procedures have been developed to theoretically simulate measured Road Rater deflections and associated stresses and strains using elastic theory as expressed in the Chevron N-layer computer program.
