Abstract:This article details how the serviceability of a flexural pavement structure is improved by incorporating the Cellular Confinement System (geocells). For this purpose, two different pavement structures, with and without embedded geocells, were manufactured in a laboratory and an accelerated traffic type of loading was applied. The vertical and horizontal cyclic loads were applied simultaneously to simulate the effect of principal stress rotation. A comparative study between the conventional flexible pavement and the geocell-reinforced flexible pavement is presented. Additionally, numerical models of the laboratory tests were built and the results were compared. The simulation of the experimental tests using the Traffic Load Simulator (TLS) are carried out using the FEM and advanced models that describe the permanent strain behavior of the unbound granular material. The development of permanent deformation within the pavement structure, with and without the geocells, is also presented through the numerical model, which was verified by the experimental results.

Title:Numerično modeliranje vozišča ojačenega z geocelicami in primerjava z laboratorijskimi eksperimenti
Abstract:Članek opisuje, na kakšen način lahko izboljšamo uporabnost fleksibilnih voziščnih konstrukcij z uporabo geocelic. V ta namen smo z laboratorijskimi preizkusi preizkušali dva tipa voziščnih konstrukcij (z in brez ojačitve z geocelicami), ki smo jih obremenjevali z dinamično obtežbo, ki je simulirala prometno obremenitev. Preizkušance smo obremenjevali istočasno tako z vertikalno kot horizonatlno obremenitvijo z namenom vzpostaviti kompleksno napetostno stanje (rotacija smeri glavnih napetosti). Predstavljena je primerjava med obnašanjem konvencionalne fleksibilne voziščne konstrukcije in voziščne konstrukcije ojačene z geocelicami. Izdelan je bil numerični model laboratorijskih preizkusov in predstavljena je primerjava z rezultati laboratorijskih obremenilnih preizkusov. Laboratorijski preizkusi so bili izvedeni z napravo TLS – simulatorjem prometnih obremenitev, medtem ko je bilo numerično modeliranje izvedeno z uporabo naprednih modelov po metodi končnih elementov (MKE), ki opisujejo trajne deformacije in napetostno stanje nevezanega nosilnega sloja iz kamnitega materiala. Razvoj trajnih deformacij voziščne konstrukcije brez in z ojačitvijo z geocelicami je prikazan na numeričnem modelu in preverjen z rezultati eksperimentov.
