Optimization and Prioritization Methods for Pavement Network Management
Given the limitations in pavement agencies’ annual budgets, one of the principal modules of a network level Pavement Management System is the economic module, whose goal is to define a network maintenance program that ensures an optimal allocation of resources. Different approaches and methods are found in literature for the resolution of the maintenance program problem, varying in the input needed information, the considered time frame and the process used to select sections, treatments and timings. This paper seeks to assess the existing methods used for the economic evaluation, prioritization and optimization applied to pavement network management and recommend the most suitable methods for different scenarios. Two main approaches (sequential and holistic) and three classes of methods (priority based on ranking and multicriteria analysis, optimization, and near-optimization methods) have been applied for solving the maintenance program problem. Holistic approach, normally solved using optimization or near-optimization methods, tackles the problem considering the overall network condition. Sequential approach is easier to implement and understand, but it may deal to solutions far from optimal because it does not consider the problem as a whole. Scenarios defining the suitability of these approaches are defined. Finally, a hybrid approach based on iterations is purposed. Iterative approach considers the overall condition of the network and is supposed to deal to better solutions than sequential approach being easier to implement and understand than the holistic approach.
