Conclusion of a framework agreement for the retrieval of measurements of tire-road noise (CPX) on undercut concrete pavement surfaces in the entire BAB network

The Concrete Construction Methods Department of the Federal Highway Research Institute (BASt) supervises various topics on surface properties and texturing of concrete pavement ceilings. As part of a comprehensive data collection for a systematic inventory, annual measurements of tire road noise (CPX) on differently textured concrete pavement surfaces throughout the BAB network are planned. In order to ensure a consistently high quality and to ensure the necessary comparability among the measurements, a framework agreement for the performance of modified CPX measurements must be concluded. The individual measurements retrieved are to be remunerated via individual statements on the basis of service units.
