Road condition surveys
To streamline the maintenance of road networks, the condition of road surfaces is assessed and the most suitable repair methods determined. Gruner Böhringer AG has provided these services for the Canton of Basel-Stadt and Canton of Basel-Landschaft Public Works Departments since 2001.
The data are collected in accordance with the relevant VSS (Swiss Association of Road and Transportation Experts) standards and entered in a database along with other road data. Road condition is assessed on the basis of indices ranging from 0 (good) to 5 (poor). The data are then used to budget for the necessary remedial works.
