Besides the technically appropriate road rehabilitation measures, the economic optimization of investment projects is becoming increasingly more important in pavement management of urban roads. To maintain the streets, each year large investments are made. Therefore, economic feasibility studies are one of the main decision-making aids by selecting the road rehabilitation and construction measures. The present Master thesis describes the assessment of savings potential in the Viennese city road network for projects costing more than 70.000 . The estimation of savings potentials is supplementary to the study research 'Economic, construction and environmental optimization of the constructive pavement surface of the Viennese city road network'(1). For this purpose in cooperation with Magistrate department 28 of the City of Vienna specific' unit costs for road rehabilitation and construction measures were derived from several years (2007-2014). On this basis, the standard measures can be evaluated and the investment cost can be compared in regard to the load class. As a result, the savings potential is determined by layer thickness reduction. In addition an overview on the bases of road pavement design was made as well as on the characteristics of urban road infrastructure in Austria and in Vienna. Moreover the economic basics were clarified (e.g. construction price index, net present value, annuity etc.) and the types of economics feasibility studies as an orientation aid for the investments comparisons.
