Transportation Asset Management Case Studies
PMS: The Washington State Experience

Conclusions

The pavement management system enables WSDOT to forecast future needs, conduct pavement performance research, and maximize pavement investments.

Washington State has seen dramatic and sustained improvement in the condition of its highway network over recent decades, concurrent with its use of regular pavement condition surveys and the WSPMS for engineering and economic analysis. The system enables WSDOT to forecast future needs, conduct research that contributes to improved pavement performance, and maximize pavement investments by objectively prioritizing highway preservation and improvement projects. In addition, the WSPMS provides a rational basis for communicating with the State legislature and highway users about stewardship of the State's infrastructure.

Although the WSPMS was developed internally and has been refined over several decades to meet the needs of WSDOT, it can serve as a model for other States. The WSPMS has features and benefits that other State departments of transportation could adapt to their specific needs at the project and system levels.
