In the early 1980s the Washington State Department of Transportation (WSDOT) implemented a new pavement management system (WSPMS) that is project specific and contains detailed construction history and performance data for all projects throughout the state. With the new WSPMS, all resurfacing designs were made with more detailed knowledge of the past performance of each project, and conflicts between design expectations and actual past performance of each project were more obvious. Using the information contained in the WSPMS and deflection data obtained from the falling weight deflectometer, WSDOT decided to develop a mechanistic, empirically based flexible pavement overlay design method and contracted with the University of Washington and the Washington State Transportation Center to cooperatively develop such a method. A general overview of this mechanistic, empirically based overlay design procedure describes subsequent implementation activities and demonstrates the application of the design procedure using a case study in which the WSDOT mechanistic, empirical design procedure is compared with other standard overlay design procedures.
