As part of the Concrete Roadway 4.0 project headed by Prof. Garrecht, Director of the Faculty's Institute of Construction Materials (IWB), a new test rig was set up at the Materials Testing Institute (MPA). This has now been inaugurated with the creation of a concrete road surface. With the facility, which was specially designed and operated for the research focus on road and pavement construction, complex issues relating to construction, materials and processes can now be investigated at the MPA on a pilot plant scale and scaled up to the real scale. In addition to all of the MPA's technical testing facilities, a correspondingly large concrete mixing plant with a volume of 1.25 m³ is available for the test stand. Regularly used and newly developed concretes can be produced here with very high mixing energies and tested directly in the test rig under real conditions.

Research project Concrete Roadway 4.0
The new test rig was developed as part of the "Concrete Roadway 4.0" research project. Since 2017, research on the road of tomorrow has been carried out at the MPA in a consortium with partners from industry and science. The goal is the digital networking of all process participants in concrete pavement construction. By optimizing the individual production steps from material, transport and paving to finishing, an improvement in production quality will be achieved. In the future, it will thus be possible to manufacture roads whose greater durability will reduce the need for maintenance work to a minimum. With the longer service life, the energy balance of road manufacture will improve to the same extent. The high social relevance of the issue is also reflected in the extraordinary funding amount of 4.7 million euros with which the project is supported by the Federal Highway Research Institute (Bundesanstalt für Straßenwesen).
