Secondary title:	Dicision making in road infrastructure maintenance: A case study of highway crossovers
Secondary abstract:	In developed economies, road infrastructure presents a significant part of the public assets. During its use, it is exposed to various deterioration processes that lead to depreciation of its financial value. It is therefore of vital importance to manage these assets so that the loss of their value with time is reduced to a minimum. A typical task of road managers is making decisions related to maintenance, repair and rehabilitation, which is based on data regarding the existing condition, risk of its use, life cycle costs, age etc. Road infrastructure is diverse, therefore the optimal choice of planned interventions is a delicate task often left to subjective judgement of road managers. The main goal of the thesis is development of a decision support system to determine the priority ranking of asset rehabilitation projects for the selected case study that consists of 27 crossovers over a highway section from Arja vas to Slivnica. An overview of the sequence of the road infrastructure management phases is first presented in the thesis. The condition of the crossovers was assessed and compared to the existing grades obtained by regular inspections. A prototype structured database that facilitates the accces to the available data was developed. Priority ranking of asset rehabilitation projects was carried out by using the developed decision support system that includes the budget constraint option. The selected set of asset rehabilitation projects meets best the pre-defined combination of several criteria and therefore results in largest overall benefit. The results show that the selection criteria employed in the decision process are crucial for the obtained results. The selected criteria should therefore reflect the actual conditions related to the assets and the needs of the users.
