Construction and maintenance of traffic routes
The basics of road construction technology with a focus on work preparation and the construction process as well as maintenance strategies for traffic routes are taught in the Bachelor's degree program. The current social challenges - climate change andCO2 emissions- are explored in greater depth in the Master's degree course. The focus here is on innovations, climate-resilient construction methods and the unsealing of traffic areas.
About our working group
Research project
The Chair of Construction and Maintenance of Traffic Routes at the University of Siegen was commissioned by the Federal Highway Research Institute (BASt) with the FE project "Investigations into the equivalence of grader and paver paving methods in the application area of layers without binders".
Excursion to a quarry
The chair stands for practice-oriented teaching. We visited the Medenbach limestone quarry with a group of around 20 people. In addition to the quarry and the demolition equipment, we were able to experience the entire rock processing process at first hand. This allowed us to demonstrate the theory taught in the lecture hall in practice.
Servo-hydraulic testing system
The department has a state-of-the-art teaching and research laboratory. Particularly noteworthy is the servo-hydraulic testing machine for addressing the performance properties of asphalt [Link: Research laboratory].
Our research profile
The construction and maintenance of transport infrastructure is subject to constant change. The priority challenges arise from international economic, ecological and social developments. Climate change and demographic developments demand resilient construction materials and highly automated construction methods, while the growing volume of traffic increasingly requires functionalized road surfaces. The Chair's research focuses are precisely tailored to the requirements of tomorrow. The Chair's team has many years of relevant expertise.
Main areas of research
- Automation and digitalization of the construction process
Ongoing work is focusing on the generation of big data during the construction process and the evaluation of this collected data with the aim of real-time quality monitoring. Real-time quality monitoring is a central component of the automation of the road construction process. - Functionalization of surfaces
The efficient production and long-term preservation of the essential surface properties of a traffic surface, the optimization of skid resistance and the reduction of rubber abrasion are the objectives of further research activities at the chair. The latest developments in process engineering are expected to produce groundbreaking results. - Temperature-reduced asphalt and resource conservation
The reduction ofCO2 emissions and the conservation of natural resources are globally defined targets, keyword Sustainable Development Goals. The process-safe production of temperature-reduced asphalts with the addition of recycled asphalts is the subject of current research proposals.
