A strategic planning scheme has been developed for a pavement rehabilitation and maintenance management system. Four usual phases compose the analysis framework: (a) problem analysis and data collection, (b) formulation of the mathematical model, (c) optimization, and (d) analysis of the solution. Matrices of roadway inventory, current pavement condition rating, gain of rating, pavement survival rate, minimum rating requirement, resource requirement, and resource availability are assembled in phase 1. In phase 2, the resource allocation problem is formulated in a zero-one integer linear programming model that maximizes the overall effectiveness of all proposed maintenance and rehabilitation activities subject to the following constraints: decision variable constraints; available supplies, equipment, work force, overhead, and state betterment budget constraints; and minimum distress rating and pavement rating constraints. The formulation of several other constraints, such as social, political, and geometric constraints, is also discussed. In phase 3, the mathematical model is used to determine the optimal maintenance strategy for each highway segment included in the analysis. Solutions are analyzed in phase 4. The formulation of this resource allocation method for strategic planning of maintenance and rehabilitation provides a basic framework within which management decisions can be made and altered while the effect that those decisions will have on the quality of pavements within a highway network can be fully recognized.
