Paper Title: An Assessment of the Benefits of Washington State Pavement Management System

Primary Author: L. Pierce

Abstract Text : Washington State Department of Transportation (WSDOT) has been collecting pavement condition data and prioritizing project selection for pavement rehabilitation since 1969. WSDOT has had a working and implemented pavement management system, referred to as the Washington State Pavement Management System (WSPMS), since 1982. As WSPMS was developed in-house, within the WSDOT Materials Laboratory, it has evolved over the years to take advantage of the advances in computing capabilities as well as changes in WSDOT pavement preservation philosophy. The most notable latest advancement is the move from programming projects for rehabilitation based on “worst first” to the “lowest life cycle cost” concept. This paper provides an assessment of the impact WSPMS had on the overall effectiveness of the WSDOT preservation program.
