Our Profile

The Institute of Highway Engineering at RWTH Aachen University has been acknowledged and recognized as an independent research institution for many years. A Material Testing Center for road construction is property of the institute. Our contractors are European Union authorities, federal road and highway authorities, municipal administration and other public institutions, industrial and road construction companies, and building materials manufacturers and suppliers. The project work always takes place through a problem-oriented approach. Solutions are developed with great expertise, motivation and innovation. If sensible, the project is carried out in interdisciplinary cooperation with other departments of RWTH Aachen or even international universities and in cooperation with planning and engineering firms, consultants or industrial and road construction companies.

As part of the project “Multiscale Modelling and Characterization of Adhesion between Bitumen and Aggregate”, we are focusing on creating fundamental knowledge of adhesion property between bitumen and aggregate at multi scales with respect to experimental tests and numerical simulation. Besides this research project, we are also committed to teaching the English courses “Environmental Sustainability in Transport Engineering” and “Pavement Dynamics”.

Join us and together with many national and international partners from industry and research, we shape a climate-friendly road system of the future!
