Predicting Critical Strains, Pavement Life, and Overlay Requirements UsingPavement Deflection Measurements

摘要

The goal of the research described in this thesis is to develop relationshipsusing measurable pavement responses to loading to predict the current pavement life and the overlay requirements. The equations are designed to be used with any pavement nondestructive testing device that can measure the pavement deflection basin. The most popular device currently in use is the FWD. The most promising new technology is a laser rolling wheel deflectometer; prototypes are being developed by Quest Integrated and the Swedish National Road Administration.
