Abstract
Cilj projektiranja kolničkih konstrukcija je odabrati najekonomičniju debljinu i sastav slojeva koji će omogućiti zadovoljavajuću razinu usluge i zahtijevati minimalno održavanje s obzirom na predviđeno prometno opterećenje tijekom životnog vijeka. Danas se najčešće primjenjuje mehanističko-empirijska metoda projektiranja. Mehanistički dio ove metode odnosi se na proračun naprezanja i deformacija u karakterističnim točkama kolničke konstrukcije kao odgovor na prometno opterećenje. Empirijski dio se odnosi na empirijski izvedene jednadžbe kojima se naprezanja i deformacije dovode u vezu s brojem ciklusa opterećenja koji rezultira oštećenjem kolničke konstrukcije. Do oštećenja kolničke konstrukcije može doći uslijed zamora materijala i pojave pukotina ili uslijed prekomjernih deformacija i pojave kolotraga. Slijedom toga razlikujemo dva kriterija određivanja dopuštenog broja ciklusa opterećenja, kriterij zamora i kriterij kolotraženja. S obzirom na empirijsku prirodu ovih kriterija ne postoj jedinstvena metoda proračuna već svaka zemlja za sebe odabire kriterije ovisno o lokalnim uvjetima. U radu se analizira utjecaj odabira između četiri modela kriterija zamora i kriterija kolotraženja na životni vijek dva tipa kolničkih konstrukcija projektiranih u skladu s normom HRN U.C4.012.
Abstract (english)
The aim of pavement design is to choose the most economical pavement thickness and composition to ensure that the pavement performs adequately and requires minimal maintenance under the anticipated traffic loading for the design life. Today, the mechanistic-empirical design method is most often applied. The mechanistic part of this method refers to the calculation of stresses and strains in critical pavement sections as a response to the traffic load. The empirical part refers to empirically derived equations that relate stresses and strains to the number of load cycles that result in pavement failure. Pavement failure can occur due to material fatigue (fatigue crack) or due to excessive plastic deformations (rutting). Consequently, we distinguish two failure criteria to predict number of allowable load repetitions. Given the empirical nature of these criteria, each country can develop its own criteria depending on local conditions from laboratory test or field performance. The paper analyzes the impact of choosing between four models of fatigue and rutting criteria on design life of two pavement types designed in accordance with the HRN U.C4.012 standard.
