Abstract
Highway authority currently face ever-increasing tasks to maintain normal functionality of a huge deteriorated roads. Allocated budget is usually small and covers 30-70% actual needs, thus the necessary maintenance is compulsorily postponed or cancelled. This fact gives us a difficult problem to be solved, whether we should aim for ensuring performance of all highways, or for generating maximum values of maintenance resources. This article therefore presents a computational procedure to prioritize maintenance in accordance with available resources. The priority indices are calculated for highway segments to determine the prioritized works and select scope of maintenance. The priority index is calculated by considering several indicators. The method have been applied to a specific highway network of Vietnam to examine whether it is useful to prioritize most necessary maintenance, such as deteriorated roads whose performance is crucial to the network.
