Abstract

Pri projektiranju kolničkih konstrukcija ključno je odabrati najekonomičniju debljinu i sastav slojeva kako bi se osigurala zadovoljavajuća razina usluge i minimalni zahtjevi za održavanje, uzimajući u obzir predviđeno prometno opterećenje. U ovom diplomskom radu provedena je analiza utjecaja odabira osovinskog opterećenja na stupanj iskoristivosti kolničke konstrukcije, a primijenjena je mehaničko-empirijska metoda projektiranja, koja se danas najčešće koristi u praksi. Mehaničko-empirijska metoda kombinira teorijske modele s empirijskim podacima kako bi se analizirala kolnička konstrukcija pod različitim osovinskim opterećenjima. U radu su uspoređeni stupnjevi iskoristivosti za ekvivalentno osovinsko opterećenje i reprezentativne vrste vozila. Rezultati istraživanja pokazuju da standardno ekvivalentno opterećenje rezultira manjom vrijednošću stupnja iskoristivosti u odnosu na mjerodavna vozila.

Abstract (english)

Pavement design requires the selection of most cost-effective layer thickness and material composition in order to ensure satisfactory service levels and minimal maintenance requirements, taking into account the expected traffic load. In this master thesis, an analysis of the influence of axle load on the pavement cumulative damage factors was performed. The mechanical – empirical design method, which is the most commonly use din practice, was applied. The mechanistic-empirical method combines theoretical models with empirical data to analyze the pavement structure under different axle loads. The cumulative damage factors for the standard equivalent axle load and the representative vehicle types are compared. The results of the study show that the standard equivalent axle load leads to a lower value of the damage factor compared to the representative vehicles.
