This report provides descriptions of processes for setting maintenance intervention criteria and allocating budgets. Due to the multi-objective nature of road asset management activities, the decision process including setting maintenance intervention criteria requires a multi-objective consideration that addresses the competing requirements of the different objectives. In this report two multi-objective methods for ranking/setting intervention criteria are described. The first is based on the analytic hierarchy process (AHP) that allows trade-off between the competing objectives and considers objectives with different units. The second method is based on life cycle cost analysis (LCCA) and considers only objectives expressed in monetary terms.
