Abstract

Izgradnja moderne cestovne infrastrukture pred sebe stavlja visoke ciljeve, kao što su utjecaj sve većeg prometnog opterećenja
i vremenskih uvjeta, te kao takva ključna je komponenta gospodarskog razvitka. Obzirom na ograničenje resursa pri izgradnji i rekonstrukciji cestovne infrastrukture, poželjno je, kod takvih projekata pronaći optimalno i racionalno rješenje. U današnje vrijeme sve je češća upotreba staklenih geomreža pri sanacijama asfaltnih kolničkih konstrukcija. Prednost takvih materijala leži u smanjenju potrebnih debljina slojeva kolničke konstrukcije, smanjenju pojave kolotraga, manjem broju reflektivnih pukotina a samim time i produženjem životnog vijeka konstrukcije. Kako bi staklena mreža mogla ispunjavati funkciju armiranja asfaltnih slojeva mora imati odgovarajuću vlačnu čvrstoću. Najčešće korištene metode ispitivanja vlačne čvrstoće su HRN EN ISO 10319 i ASTM D6637/6637M-15. U radu je prikazan utjecaj načina ispitivanja vlačnih svojstava staklenih mreža (prema HRN EN ISO 10319 ili prema ASTM D6637/6637M-15) na dobivene rezultate.

Abstract (english)

The construction of modern road infrastructure has high goals, such as the impact of increasing traffic congestion and weather conditions, and as such is a key component of economic development. Given the limited resources in the construction and reconstruction of road infrastructure, it is desirable to find an optimal and rational solution for such projects. Nowadays,
the use of glass geogrids in the rehabilitation of asphalt pavement structures is becoming more common. The advantage of such materials lies in the reduction of the required thicknesses of the layers of the pavement structure, the reduction of the appearance of ruts, a smaller number of reflective cracks and thus the extension of the service life of the structure. In order for the glass grid to fulfill the function of reinforcing asphalt layers, it must have adequate tensile strength. The most commonly used tensile strength test methods are HRN EN ISO 10319 and ASTM D6637/6637M-15. The diplom work presents the influence of the method of testing the tensile properties of glass grids (according to HRN EN ISO 10319 or according to ASTM D6637 / 6637M- 15) on the obtained results.
