Managing Network-Level Pavement Condition: An Integer Programming Approach

Pavement network conditions deteriorate over the years of usage. To keep pavement conditions at an acceptable level, highway agencies plan pavement maintenance and rehabilitation (M&R) programs and perform them accordingly. Highway agencies usually face budget uncertainties for pavement maintenance and rehabilitation activities due to limited resources and changes in government policies. The situation makes it difficult for highway agencies to keep a stable pavement condition at the network level. Therefore, it is important for highway agencies to adopt maintenance and rehabilitation policies that can manage pavement condition at the network level. In this paper, a multi-period multi-objective nonlinear integer programming model is proposed. Two objectives, maximization of average network condition and minimization of fluctuation of network condition from a smooth condition score linear function, are considered in the formulation. The model is formulated for chance constrained M&R budgets. The proposed model provides a maintenance and rehabilitation program for the pavement network that results in stable network conditions. A case study examining a hypothetical network of 25 pavement sections is conducted. The solutions for different chances of budget constraint are presented. Also, the value of the system to the decision maker is discussed. The results show that the proposed model is a practical and flexible way to handle management of pavement maintenance at the network level.
