Popis:	Opisani su konstrukcijski i tehnološki aspekti gradnje velikih lučnih mostova s montažnim odsječcima primjenom betona od reaktivnog praha. Odsječci se izrađuju betoniranjem sukladnih sljubnica, spajaju epoksidnim smolama i potom prednapinju vanjskim čeličnim šipkama samo na dijelu spojnica. Lukovi se izvode zrakastim ovješenjem konzola preko petnih stupova, a grede obostranim potiskivanjem bez klasičnog kljuna s istodobnim postavljanjem stupova s grede i reguliranjem visine nivelete. Structural and technological aspects in the construction of large-span arch bridges, characterized by the use of prefabricated segments and reactive powder concrete, are described. Segments are realized by concreting corresponding joints, and are then linked with epoxy resins and prestressed with external steel bars but only in the joint zone. Arches are erected by radial suspension of cantilevers over abutment piers, while beams are realized by two-sided pushing without traditional nose, with simultaneous positioning of piers from the beam and regulation of the grade line.
