The WSDOT Pavement Management System: Operational Enhancements

This report documents potential enhancements in three areas for the Washington State Pavement Management System (WSPMS): (1) a checking scheme for the annual pavement condition survey, (2) models for use in estimating vehicle operating costs due to pavement deterioration and their use in the optimal timing of rehabilitation, and (3) an alternate method for estimating pavement performance equations. The earlier report for this study (WA-RD 315.1, "Statistical Methods for WSDOT Pavement and Material Applications") provides an overview of various statistical methods. A purpose of that report was to explain statistical methods (with special emphasis on regression analysis) in a straightforward manner to a broad group of users.
