Funding crisis & meeting pavement preservation goals
Risk: declining funding: § Maintaining over 20,000 lane miles while funding dropped by $600 million in 10 years (27% reduction) Mitigation strategies: Create efficiencies § Target lowest life-cycle cost – WSDOT achieves pavement condition goals amidst funding crisis
*Note: Projections as of December 2011.

WSDOT’s pavement technology innovations help offset declining investments
WSDOT uses pavement technology to make the state’s roads last longer and cost less. Efficiencies include: § Dowel bar retrofits on concrete pavements § Selective panel replacement and diamond grinding on concrete pavements § Converting higher cost asphalt pavements to lower cost chip seal pavements ($151 million saved as of December 2011)

Decisions and Outcomes
Uses for Economic Performance Methodologies
- Evaluation of Pavement Management
§ How efficiently are pavements performing? § Are the most cost-effective decisions being implemented?
- Evaluation of Pavement Design
§ Is pavement structure over designed or under designed?
- Evaluation of Freight Corridors
§ Are freight corridors designed with the most efficient pavements?
