Contracting and maintenance privatization are increasingly being used by state DOTs in response to the public-private partnerships (PPP) that is gaining popularity in the U.S. Under this context, a systematic methodology for pavement maintenance programming is of great value to the private organizations that contract outcome-based pavement network maintenance from state departments of transportation (DOTs). Ideally, the private road manager may wish to find suitable maintenance strategies that minimize the total maintenance cost while simultaneously maximizing the network performance. This paper proposes a practical decision-support model for determining optimal network-level maintenance policies based on goal programming. The model can handle the aforementioned incommensurable and conflicting objectives while considering probabilistic constraints related to the available budget. The implementation of the model in a simple case study showed that its application is practical for supporting the management of pavement networks to achieve specific performance targets while controlling costs. The proposed model can help balance the private sectors' goals, resource limitations, and performance targets under a warranty contract.
