In modern society, road infrastructure represents the foundation of economic and social development, as it enables efficient and safe mobility of people and the flow of goods. Of particular importance are large span bridges and viaducts, which enable transport connections on more demanding terrain and significantly affect the integrity of the transport system. They must be able to withstand loads, external influences and possible hidden defects and maintain functionality over a long period of time. Therefore, in the engineering design and management of viaducts, the concept of structural robustness is receiving increasing attention. Robustness is the ability of a structural system to maintain its basic function in the event of unexpected events, damage or defects without collapsing or significant loss of load-bearing capacity. In road infrastructure, robustness is essential for ensuring safety, resistance to extreme impacts and ensuring operational reliability. Viaducts, as an important part of the highway network, are particularly vulnerable to various damage scenarios due to their exposure to weather and traffic loads, as well as the complexity of their structural design and maintenance requirements. Therefore, analysing their robustness is important for planning, construction and maintenance. This thesis aims to analyze the robustness of viaducts on the Slovenian motorway network using data from the DARS Bridge Structure Monitoring System, the Road Data Bank and the open data of the Republic of Slovenia [1]. The analysis uses the robustness indicators and the AHP multi-criteria decision-making method [2] to compare viaducts. Based on the classification, a transparent scale is created that identifies structures with the highest and lowest robustness, providing the basis for priority maintenance and renovation measures and ensuring the long-term safety and sustainability of the motorway network.
