Abstract

Prilikom dimenzioniranja kolničke konstrukcije, različit utjecaj i konfiguracija osovina, preko faktora ekvivalencije (LEF) svodi se na utjecaj ekvivalentne standardne osovine (ESAL). Faktor ekvivalencije ili LEF predstavlja prosječni štetni utjecaj pojedinih osovinskih opterećenja vozila na kolničku konstrukciju u odnosu na utjecaj standardne osovine od 80 kN. Dok je standardna osovina (ESAL) jednostruka osovina s dva dvostruka kotača koja prenosi opterećenje od 80 kN, uz pretpostavku jednolike raspodijele opterećenja po kotačima. U okviru ovog diplomskog zadatka proveden je proračun i grafički je prikazan utjecaj porasta ukupne težine teških teretnih vozila za 5, 10, 15 i 20 %. Proračun je proveden pomoću norme HRN U.C4.010. Vozila koja su odabrana za proračun, reprezentativna su za današnje vrijeme, takva vozila nisu prikazana normom, a utjecaj njihova opterećenja je značajan pri dimenzioniranju kolničkih konstrukcija. U radu je prikazan način proračuna prometnog opterećenja u drugim europskim zemljama poput Slovenije, Italije, Njemačke, Nizozemske i Švedske. Većina tih zemalja, kao i Hrvatska, temelji proračun na AASHO (American Association of State Highway Officials) Road Testu.

Abstract (english)

During dimensioning the pavement structure, the different influence and configuration of the axles is reduced to the influence of the equivalent standard axle (ESAL) via the equivalence factor (LEF). Equivalence factor or LEF represents the average harmful impact of individual vehicle axle loads on the pavement structure, compared to the impact of a standard axle of 80 kN. While the standard axle (ESAL) is a single axle with two double wheels carrying a load of 80 kN, assuming uniform load distribution over the wheels. As part of this thesis, a calculation was carried out and the impact of an increase in the total weight of heavy goods vehicles by 5, 10, 15 and 20% and it was graphically presented. The calculation was carried out using the norm HRN U.C4.010. The vehicles selected for the calculation are representative for nowadays, such vehicles are not shown by the norm, and the impact of their load is significant when dimensioning pavement structures. The thesis presents the method of calculating the traffic load in other European countries such as Slovenia, Italy, Germany, the Netherlands and Sweden. Most of these countries, as well as Croatia, base their calculation on the AASHO (American Association of State Highway Officials) Road Test.
