Sažetak
Road markings represent an important element of modern road surfaces. In order to ensure their satisfying quality, they need to be periodically tested. The quality of road markings is determined by measuring their visibility since this is their most important characteristic. During the application of road markings, a layer of “fog” is applied on the retroreflective material, i.e. glass beads. In the course of exploitation, this layer is slowly being removed, which causes the increase of retroreflection to a certain level. In that respect, the period after the application during which the tests are conducted differs in most EU countries, depending on the country’s technical guidelines. For this reason, the aim of this paper is to determine the “peak point” of road markings retroreflection in order to define a universal time interval in which the visibility of the markings should be tested after their application. The research included five single carriageway roads with thermoplastic markings and five roads with markings made of solvent-borne paint. The results indicate that the thermoplastic markings will reach maximum retroreflection after 13.20 days, while solvent-borne paint markings after 9.80 days.
