NETWORK LEVEL OPTIMIZATION/PRIORITIZATION OF PAVEMENT REHABILITATION

A procedure has been developed to optimize pavement rehabilitation strategies for the highway network in Mississippi. The methodology is developed in two stages: project level and network level. First, at the project level, a set of feasible double-action strategies and the corresponding times of implementation of each alternative of every strategy are determined. The optimum rehabilitative strategies are selected by maximizing pavement performance for a 12-yr analysis period. A univariant search technique is employed to solve for the nonlinear optimization problem. The second part of the analysis deals with network level optimization. Selection of the set of projects is done by maximizing pavements performance weighted with respect to traffic. The projects for rehabilitation for the next 12 years are selected using a 0-1 interger linear program, which, for computational convenience, is transformed into a dynamic program. The final results of the two-stage analysis are the selection and timing of major rehabilitative activities. An example problem involving 39 sections (250 two-lane miles) of Interstate highways in north Mississippi is solved, and salient results are presented in the report.
