This article presents the development and implementation of a multi-objective decision-aid tool (MODAT) which considers different possible goals: minimisation of agency costs; minimisation of user costs; maximisation of the residual value of pavements, etc. The MODAT uses the deterministic pavement performance model used in the AASHTO flexible pavement design method. The application of the new decision-aid tool is illustrated with a case study involving the main road network of Castelo Branco, a district of Portugal. The knee point, which represents the most interesting solution of the Pareto frontier, corresponds to an agency cost weight value of 81% and a weight value of 19% for the residual value of pavements, demonstrating that agency costs, because they are generally much greater than residual value of pavements, dominate the decision process.
