Federal Highway Research Institute

Demonstration and investigation sections

Innovative road constructions that have been developed in the course of the “Roads in the 21st Century” research programme and by partners in industry are currently being tested in projects. In addition, open stretches for conducting trials and tests and demonstrating new technologies can be assigned on request.
