Özet

In order to provide traffic safety on the road, the skid resistance should be at a certain level between the wheel and the surface of the pavement. Skid resistance on which road safety depends is closely related to the pavement surface texture.. The deformations especially the polishing effect seen on the surface of wearing course due to the traffic loads, involves a change in the surface texture. In recent years, efforts are performed to develop more advanced technologies for evaluating pavement surface texture. In this study, the 3D laser scanner was utilized to quantify the mean profile depth (MPD) of 4 different types of flexible pavement in Izmir according to ASTM E 1845-09. The results have been compared with the results of sand patch test (MTD) and skid resistance test result for a period of 3 months. The results indicated that a close correlation exists between MTD and MPD values. Besides the variation of reduction in IVIPD values in not the same as the friction value corresponding to 60 km/h speed (f(60)).
