Abstract
U diplomskom radu je opisana primjena georadara (Ground Penetrating Radar-GPR) pri određivanju debljine slojeva kolničke konstrukcije. U cilju ocjene točnosti određivanja debljine slojeva kolničke konstrukcije GPR metodom, provedena su mjerenja GPR antenama 1 GHz i 2GHz za dva načina rada sustava, u pokretu i stacionarno. Na lokacijama GPR mjerenja su provedeni istražni radovi temeljem kojih je utvrđena stvarna debljina slojeva. Ocjena točnosti GPR mjerenja provedena je usporedbom debljina slojeva izmjerenih na istražnim bušotinama i onih dobivenih interpretacijom GPR mjerenja za različite antene i načine rada sustava. Rezultati mjerenja pokazuju da je za ukupnu debljinu asfaltnih slojeva manja vrijednost relativne pogreške dobivena za mjerenje 1 GHz antenom, dok je za mehanički zbijeni nosivi sloj manja vrijednost relativne pogreške dobivena za mjerenje 2 GHZ antenom. U odnosu na način rada sustava za oba sloja veća točnost je dobivena pri stacionarnom mjerenju.
Abstract (english)
The master thesis describes application of Ground Penetrating Radar (GPR) for determination of pavement layer thickness. In order to evaluate the accuracy of pavement layer thickness by GPR method, measurements were made with 1 GHz and 2 GHz GPR antennas for two modes of data collection, in motion and stationary. Investigation works were carried out at the locations of GPR measurements, and the actual thickness of the layers was determined on boreholes. The evaluation of the accuracy of the GPR measurements was carried out by comparing the thicknesses of the layers measured on the boreholes and those obtained by the interpretation of the GPR measurements for different antenna frequency and data collection modes. The measurement results show that for the total thickness of the asphalt layers, a smaller value of relative error was obtained for measurement with a 1 GHz antenna, while for a unbound granular base layer, a smaller value of relative error was obtained for measurement with a 2 GHZ antenna. In relation to the data collection modes for both layers, higher accuracy was obtained during stationary measurement.
