The Technology Directorate tested the skid resistance of secondary main roads in Győr-Moson-Sopron County on an overall length of 520 km. A comprehensive assessment of pavement roughness characteristics is important not only on busy or high-risk sections, but on the secondary public road network and municipal roads as well. By being aware of pavement roughness data, it is possible to identify locations posing high risks of accidents, and propose reconstruction works and technologies.
