With such factors as an aging national infrastructure, increasing congestion, expanding traffic, and limited funds weighing heavily on transportation agencies, State departments of transportation are looking for innovative ways to manage and maintain their transportation assets. One tool that continues to provide great benefits is Transportation Asset Management (TAM), a strategic approach that strives to provide the best return for each dollar invested by maximizing system performance, improving customer satisfaction, and minimizing life-cycle costs. TAM practices influence transportation decisionmaking by providing decisionmakers with powerful tools to help identify priorities. Pavement management systems can be effectively used to perform engineering analysis to improve design, construction, and preservation practices and to support decisionmaking processes by prioritizing pavement preservation and rehabilitation needs. This case study provides good examples of the Washington State Department of Transportation's application of their pavement management system for economic and engineering analysis. |
