Abstract

Diplomsko delo predstavlja splošen opis voziščne konstrukcije, sledi dimenzioniranje voziščne konstrukcije z uporabo tehničnih specifikacij za javne ceste ter izračun napetostno deformacijskega stanja v nevezani nosilni plasti. Izračun napetosti in deformacij izvedemo po metodi končnih elementov z uporabo geotehničnega programa Plaxis. Dobljene rezultate analiziramo in jih primerjamo z izmerjenimi rezultati na terenu. V drugem delu diplomske naloge so na praktičnem primeru uporabe murskih prodov prikazani rezultati laboratorijskih preiskav različnih mešanic murskega proda in s pomočjo matematičnih metod izračunane napetosti in deformacije. Rezultati pokažejo, da se z uporabo drobljenih prodov trajne deformacije v nevezani nosilni plasti bistveno zmanjšajo.

Secondary title:	Design of pavement structure with regard to permanent deformation in unbound paving layers
Secondary abstract:	Diploma presents general description of pavement structure, then follow design of pavement structure with use of technical specifications for public roads and calculation of stresses and strains in unbound paving layers. Calculation of stresses and strains are made with finite element method with use of geotechnical program Plaxis. The obtained results were analyzed and compared with measured results on the ground. The second part of diploma is a practical example of Mura gravel and shows the results of laboratory tests of different mixtures of Mura gravel. Stresses and strains are calculated using different mathematical methods. The results showed that the crushing of Mura gravel substantially reduced permanent deformation of unbound paving layer.
