Pavement Management Systems: Opportunities to Improve the Current Frameworks

Pavement management systems have emerged as an effective tool for allocating resources for the maintenance and rehabilitation of pavement networks. The goal of this paper is to benchmark the existing literature in order to facilitate a better understanding of the opportunities to augment the current frameworks while remaining consistent with the aims of the Moving Ahead for Progress in the 21st Century (MAP-21) Act. Key themes that emerge include the need to (a) consider sources of uncertainty beyond pavement deterioration, (b) preserve and utilize multi-attribute condition information in a more efficient manner, and (c) reach a consensus on the objective functions of relevance. Addressing these three areas, in the opinion of the authors, will place the pavement management community in a better position to maintain existing assets in the face of limited resources and an uncertain future. The authors demonstrate the need to incorporate uncertainty for a larger range of inputs than currently implemented by developing a case study that evaluates the implications of uncertainty in future costs. Two methodologies are used; the first transforms stochastic uncertainty into a deterministic constraint, while the second is a locally optimal algorithm that makes the best decision at each time step as uncertainty evolves. Results suggest that (a) cost uncertainty has implications on the optimal maintenance strategy and (b) allowing decisions to evolve over time can lead to improved performance compared to finding the globally optimal decision at once.
