The majority of the known and popular bridges in Slovenija are very old, some of them were buit 2-3 centures ago (Zmajski most – 1901, the middle bridge of the 3 bridges Tromostovlje – 1842). Almous all of these historic famous bridges are built out of stone and appart from having their basic purpose, they also have historic and cultural value, so because of that they are renovated very often. Bridge-building in Slovenia expanded and became more frequent when the country began with the building of highways (first highway was on relation Vrhnika – Postojna , oppened in 1972) and from that point, began the building of lots of bridge-like objects (viaducts, underpasses, overpasses etc.). If we look at the material, most of those bridges and viaducts are reinforced concrete bridges. Given that these structures are exposed to a lot of external influences all the time, a lot of damadges appear, which is a reason for them to be mantained reggulary. Also, it has to be decided for the means of maintainance, with the always limited financial resources taken into account. If we want to achieve the most effective reconstruction that will also be the most financialy accetable, we have to use the most rational approaches and methods in the reconstruction plans.
My bachelor diploma seminar paper is basically, the deciding tool of choosing the optimal set of meassures taken for the rehabilitation of one existing bridge, from the whole set of possible actions for rehabilitation.
