Variant solutions for the reconstruction of local road LC69038 Duba Stonska-Luka, section Rusan-Luka

Zbog lošeg stanja kolnika, horizontalnih i vertikalnih elemenata trase te elemenata poprečnog presjeka neusklađenih sa zahtjevima važeće regulative, znatan dio postojećih prometnica na poluotoku Pelješcu ne zadovoljava suvremene standarde, zbog čega je planirana njihova rekonstrukcija. U radu je prikazana izrada dvaju varijantnih rješenja rekonstrukcije lokalne ceste na tom poluotoku - LC69038 (Duba Stonska-Luka), na dionici Rusan-Luka, u duljini od jednog kilometra. Rekonstrukcija ceste provedena je izmjenom poprečnog presjeka i geometrije trase za 5. kategoriju ceste i dvije projektne brzine (40 i 50 km/h), temeljem odredbi Pravilnika o osnovnim uvjetima kojima javne ceste izvan naselja i njihovi elementi moraju udovoljavati sa stajališta sigurnosti prometa NN 110/2001. U sklopu rada izrađeni su sljedeći grafički prilozi: situacija varijantnih rješenja, uzdužni profili na duljini od 500 metara trase, normalni poprečni profili te po deset karakterističnih profila za svaku varijantu, na razmaku od 50 metara. Usporedbom varijantnih rješenja kao optimalna varijanta rekonstrukcije odabrana je varijanta za projektnu brzinu od 40 km/h.Most roads located on the Pelješac peninsula do not meet the modern standard, due to the poor pavement condition, as well as horizontal and vertical alignment that, together with cross- section elements do not comply with the current road design regulations. This undergraduate thesis covers the design of two variant solutions for the reconstruction of the local road on this peninsula - LC69038 Duba Stonska-Luka, on the section Rusan-Luka, approximately one kilometer long. The reconstruction design, which included the upgrade of cross-section elements and the elements of horizontal and vertical alignment, was carried out according to the provisions of the “Ordinance on the basic conditions that public roads outside the settlement and their elements must meet from the point of view of traffic safety, Official Gazette 110/2001” for the road category no 5 and two design speeds: 40 and 50 km/h. The thesis contains the following graphic attachments: plan views, longitudinal profiles for 500 m long road sections, standard cross-sections, and characteristic cross-sections, 10 for each reconstruction variant. By comparing the variant solutions, the variant for the design speed of 40 km/h was selected as the optimal for the reconstruction
