When faced with budget constraints, road asset managers need to prioritise and justify budget allocations between maintenance programs related to different assets and ensure acceptable levels of service (LOS) for all. As a result of the prioritisation process, which is usually based on economic evaluation, some activities are not funded and gaps in infrastructure performance will not be addressed. This may necessitate revising the LOS that could be achieved and trigger changes to asset maintenance intervention criteria (intervention level and/or response time). This paper describes a multi-objective resource allocation process (RAP) that could be used to assist in optimising budget allocations among assets and in trading-off intervention criteria across the different assets to meet a budget limit and achieve acceptable LOS. The RAP is based on a multi-criteria analysis technique called the Analytic Hierarchy Process (AHP). (a) For the covering entry of this conference, please see ITRD abstract no. 0612AR242E.
