Abstract

Tema ovog diplomskog rada je projekt sanacije državne ceste D44 temeljem podataka mjerenja defleksija FWD uređajem. U radu se daje naglasak na nerazorne metode ispitivanja strukturalnog stanja kolničkih konstrukcija na temelju izmjerenih defleksija. Daljnjom obradom podataka, takva mjerenja mogu otkriti nekoliko činjenica o postojećem stanju izgrađene kolničke konstrukcije. U radu su prikazani razni načini prikupljanja podataka i izračuna vrijednosti na temelju kojih se određuje stanje kolnika. Među prvim i jednostavnijim načinima određivanja strukturalnog stanja bilo je na osnovu vrijednosti izračunatih parametara krivulje defleksija pomoću uređaja s padajućim teretom (FWD). FWD jedan je od najraširenijih nerazornih mjernih uređaja kojim se određuje strukturalno stanje kolnika. Široko je korišten u inženjerstvu kolničkih konstrukcija za procjenu stanja konstrukcije kolnika. Mjerenjem FWD-om jedan od glavnih ciljeva je bio odrediti mjesta smanjene nosivosti kolničke konstrukcije na dionici Bršćak – Lupoglav, državne ceste D44. Na temelju interpretiranih defleksija, dostupnih podataka o prometu i podataka terenskih istražnih radova dimenzionirana je kolnička konstrukcija promatrane dionice. Uvažavajući podatke o sastavu i kvaliteti materijala slojeva kolničke konstrukcije te na temelju prijedloga sanacije u radu je provedena provjera strukturalnog kapaciteta sanirane kolničke konstrukcije.

Abstract (english)

The subject of this graduate thesis is the rehabilitation project of D44 state road based data from the measurement of deflections by FWD device. The paper focuses on non-destructive methods of testing the structural condition of pavement constructions based on measured deflections. Such measurements by further processing the data can reveal several facts about the existing state of the built roadway. Various ways of collecting data are presented by measuring and calculating the values from which the state of the roadway is determined. Among the first and simpler ways to determine the structural state was based on the values of the calculated parameters using a falling weight deflectometer (FWD). FWD is one of the most widespread non-destructive measuring devices used to determine the structural condition of pavements. It is widely used in pavement engineering to assess the condition of pavement structures. By measuring with FWD, one of the main aims was to determine the places of reduced load bearing capacity of the road structure on the section Bršćak – Lupoglav, state road D44. Based on the interpreted deflections, available traffic data and data from field research, the pavement structure of the observed section was dimensioned. Taking into account the data on the composition and quality of the material of the pavement structure layers and on the basis of the rehabilitation suggestions, the structural capacity of the repaired pavement structure was checked.
