ANALYSIS OF FULL DEPTH AC PAVEMENTS USING LAYERED ELASTIC THEORY
Full depth AC pavements constructed near Indio, Blythe, and Willits, California, were instrumented during construction and subsequently tested, using slow speed loads, to measure in-situ stress, strain, and deflection. In-situ pavement temperatures and subgrade moisture contents were also measured. An interim report describing the components and procedures used for this instrumentation was published in 1973. The data have now been used to evaluate a theoretical pavement analysis procedure incorporating layered elastic theory that was under consideration as an addition to the Caltrans structural section design procedure. Due to the questionable validity of the in-situ measurements, the accuracy of the layered elastic theory approach studied could not be conclusively determined. It was concluded that the apparent instrumentation difficulties encountered will have to be overcome before a conclusive evaluation of the layered elastic theory approach can be completed.
