Description:

Presented in this report are the results of an investigation of the capability of linear elastic theory to predict measured displacements on the surface, within·, and beneath flexible pavement structures. In measuring predictive capability, the yard stick used was replication error. Sources of data were an NCHRP project, the AASHO Road Test, and the Texas Transportation Institutes Flexible Pavement Test Facility. Only the Texas source, which employed a vibrating surface load (the Dynaflect) and specially designed transducers lowered into small-diameter measurement holes, furnished both horizontal and vertical displacements. These were measured at various depths ranging from zero to 65 inches beneath the pavement surface, and at horizontal distances ranging from 10 to 216 inches. An analysis of a selected portion of the Texas data, using the theory of elastic layered systems as a model, yielded prediction errors that were reasonably commensurate with replication error.
