The main cases of specific superstructure loading by process equipment, mechanisms, and transit traffic are identified.<\/p>\n<p style=\"text-align: justify;\">The authors present a comprehensive analysis of the performance of a composite superstructure during the driveway slab replacement during the dismantling phase. It is determined that the load-bearing capacity of the main beams is ensured. However, certain structures, particularly transverse ties, do not ensure stability during the implementation of the work; recommendations for their reinforcement are provided. The article clearly confirms that the key condition for the successful reconstruction of composite bridges along half the roadway during the production process is the construction of a temporary support under the superstructure.<\/p>\n<p style=\"text-align: justify;\">The article presents an example of the reconstruction of composite superstructures according to standard design 43282KM for the bridge across the Bystraya River in Kamchatka Krai using a temporary support. This serves as a full-scale demonstration of the implementation of individual research results. The positive values obtained for the design coefficient as a result of static tests confirm the effectiveness of the proposed solutions for converting the superstructure to an all-metal one.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<\/strong> composite superstructure; reconstruction; temporary support; temporary bridge; reinforced concrete roadway slab; orthotropic metal deck; bridge static tests; design coefficient<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Shevchenko Nikita Sergeevich Pacific National University, Khabarovsk, Russia E-mail: nik_shev_most@mail.ru ORCID: https:\/\/orcid.org\/0009-0003-9725-2828 RSCI: https:\/\/elibrary.ru\/author_profile.asp?id=1214570 Kamenchukov Aleksey Viktorovich Pacific National University, Khabarovsk, Russia E-mail: 006641@togudv.ru ORCID: https:\/\/orcid.org\/0000-0001-7997-3195 RSCI: https:\/\/elibrary.ru\/author_profile.asp?id=767839 SCOPUS: https:\/\/www.scopus.com\/authid\/detail.url?authorId=57207104736 Piotrovich Aleksey Anatolyevich Far Eastern State Transport University, Khabarovsk, Russia &hellip;<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[59,5],"tags":[],"class_list":["post-2814","post","type-post","status-publish","format-standard","hentry","category-issue-4-2025","category-article"],"_links":{"self":[{"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/posts\/2814","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/comments?post=2814"}],"version-history":[{"count":1,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/posts\/2814\/revisions"}],"predecessor-version":[{"id":2815,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/posts\/2814\/revisions\/2815"}],"wp:attachment":[{"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/media?parent=2814"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/categories?post=2814"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/t-s.today\/en\/wp-json\/wp\/v2\/tags?post=2814"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
