Abstract

U diplomskom radu opisan je postupak ocjene stanja kolnika prema COST Action 354 indikatorima ponašanja. Na temelju podataka o uzdužnoj ravnosti, dubini kolotraga, teksturi, pukotinama i nosivosti izračunate su vrijednosti pojedinačnih indikatora ponašanja na dionici autoceste A3 (Bregana-Zagreb-Lipovac). Proračunate vrijednosti pojedinačnih indikatora korištene su za izračun kombiniranih indikatora udobnosti, sigurnosti i nosivosti na temelju kojih su dobivene vrijednosti općeg indikatora ponašanja. Prema vrijednostima općeg indikatora ponašanja stanje kolnika na poddionici 1 procijenjeno je kao loše na 40%, zadovoljavajuće na 12%, dobro na 26% i vrlo dobro na 23%, a na poddionici 2 loše na 61%, zadovoljavajuće na 30% i dobro na 9%. Glavni doprinos lošoj ocjeni stanja kolnika ima pojedinačni indikator pukotina.

Abstract (english)

The master's thesis describes the procedure for pavement condition based on the performance indicators of COST Action 354. Based on data on longitudinal evenness, rut depth, texture, cracking and bearing capacity, the values of individual performance indicators were calculated on the A3 highway section (Bregana-Zagreb-Lipovac). The calculated values of the individual indicators were used to calculate the combined performance index for comfort, safety and bearing capacity, based on which the values of the general performance indicator were determined. According to the values of the general performance indicator, the condition of the pavement was rated as poor on 40% of the highway subsections 1, fair on 12%, good on 26%, and very good on 23%, and on highway subsection 2 as poor on 61%, fair on 30% and good on 9%. The majority of the poor pavement condition rating was due to the individual cracking performance indicator.
