Evaluation of Maintenance Effectiveness for WSDOT Pavement Network

Any economical extension of pavement service life has a significant benefit for long-term life-cycle costs. Pavement maintenance activities can substantially extend the pavement service life or keep it from prematurely failing. The simple concept of higher costs due to deferred maintenance becomes more complicated when the objective is quantifying the cost tradeoffs, and selecting among maintenance alternatives. Current budget constraints in Washington State necessitate the development of new strategies with regard to pavement maintenance and preservation. Even if the optimum long-term rehabilitation plan for a particular section of roadway calls for a rehabilitation project, there often are no funds available to program the construction. This situation has resulted in the development of maintenance strategies for the purpose of delaying or avoiding pavement rehabilitation spending. These strategies include: (1) addressing early distress, (2) correcting short distressed sections, (3) maintaining and “holding” sections that are currently due for rehabilitation, and (4) integrating maintenance with rehabilitation strategies. The focus of this paper is to evaluate the effectiveness of different pavement maintenance strategies, and improve the procedures for analyzing maintenance tradeoffs. To illustrate the impacts of the maintenance strategy on a network level, three pavement preservation alternatives are compared, and associated costs are estimated for the Washington State pavement network.
