Investment in its construction and maintenance is significant on a global scale. Previously published life cycle assessment (LCA) studies performed on road and rail systems very seldom included infrastructures in detail, mainly choosing to focus on vehicle manufacturing and fuel consumption. This article presents results from an environmental study for railway steel bridge materials for the demonstration case of the Buna Bridge in Croatia. The goal of these analyses was to compare two different types of remediation works for railway bridges with different materials and construction types. In the first part, the environmental impact of the classical concrete bridge construction was calculated, whereas in the second one, an alternative new solution, namely, the strengthening of the old steel bridge with ultra-high-performance fibre-reinforced concrete (UHPFRC) deck, was studied. The results of the LCA show that the new solution with UHPFRC deck gives much better environmental performance. Up to now, results of LCA of railway open lines, railway bridges and tunnels have been published, but detailed analyses of the new solution with UHPFRC deck above the old bridge have not previously been performed</dc:description><dc:description xml:lang="sl">Železniška infrastruktura je zelo pomemben del celo - tnega transportnega omrežja. Gradnja in vzdrževanje prog tudi v svetovnem merilu predstavlja velik strošek. Dosedanje LCA študije (analiza življenjskega cikla), iz - vedene na cestnih in železniških omrežjih zelo redko vključujejo podrobno analizo infrastrukture, večino - ma se osredotočijo na porabo goriva za proizvodnjo in pogon vozil. V prispevku so predstavljeni rezultati iz okoljske študije za uporabljene materiale železniškega mostu %Buna most% na Hrvaškem. Cilj te analize je bil primerjati dve različni metodi sanacije starega mostu s poudarkom na uporabi različnega materiala in za različne tipe konstrukcij. V prvem delu je bil izračunan vpliv na okolje za klasično betonsko konstrukcijo mo - stu, medtem ko je v drugem prikazan izračun za novo alternativno rešitve sanacije mostu; ojačanje starega jeklenega mostu s UHPFRC (mikroarmiran beton zelo visokih zmogljivosti) ploščo. Rezultati LCA kažejo, da ima nova rešitev z UHPFRC ploščo veliko manjši vpliv na okolje kot klasična betonska konstrukcija. Do sedaj objavljene LCA študije so se večinoma osredotočale na analize gradnje in sanacije odprtih železniških prog, železniških mostov in predorov. Za novo alternativno metoda, sanacije železniškega mostu z UHPFRC ploščo, okoljska LCA analiza do sedaj še ni bila objavljena</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-HVFB6PX6"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-HVFB6PX6" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-HVFB6PX6/664ab01f-2727-4074-8a75-e2a38cd448cc/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Naravoslovnotehniška fakulteta</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-HVFB6PX6/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-HVFB6PX6" /></ore:Aggregation></rdf:RDF>
