The Institute of Highway Engineering Aachen has been acknowledged and recognized as an independent research institution for decades, in basic research as well as in application-oriented research. By diversifying the research spectrum, we are able to expand our core competencies and pass on the know-how to our customers continuously.isac
The research activities of the institute in the field of road construction technology focus on a future-oriented, progressive and modern infrastructure, taking into account the needs of road users, the environment and construction companies.
The aim is to maximize the functionality and durability of pavements by optimizing existing pavements on the market and developing new road pavement materials. This is done taking into consideration the entire life cycle of the roadway, from the production of the building materials and paving to the assessment of the quality of the roadway system in operation. The institute has comprehensive "know-how" in the field of simulation-supported as well as experimental investigation methods.
The following research areas are currently under discussion:
Bitumen & Asphalt:
- Development of analytics for advanced bitumen & asphalt testing
- Optimization of the properties of bitumen at the molecular level
- Optimization of the performance properties of asphalts
Multifunctional road building materials:
- Development of water-permeable road pavements made of alternative building materials
- Market placement of novel road construction materials based on polyurethane
- Expansion of the function of the traffic area towards energy generation
Dimensioning & maintenance:
- Superstructure dimensioning for asphalt and concrete fixings
- Development of numerical simulation methods to evaluate crack formation and propagation in asphalt superstructures
- Development of multi-scale models to assess the durability of asphalt structures
Installation & Quality:
- Optimization of asphalt paving and compaction processes
- Optimization of the quality of asphalt pavements, including the paving and compaction process
Development of methods for non-destructive load-bearing capacity measurement and evaluation of the road superstructure
- Development of noise-reducing road surfaces based on plastic
- Non-contact condition detection of flatness and skid resistance
- Evaluation of the macro- and microscopic surface topography with regard to its effect on flatness and skid resistance
The Institute of Highway Engineering deals with central topics of road planning and equipment, the traffic flow as well as road safety.
The topics of the road planning work are all questions concerning the influence of traffic, taking into account parameters of traffic safety and quality as well as the investigation of the effects of workplaces and their optimization on federal motorways.
A further research area is the investigation of the psychological perception and effect on the driver of spatial routing elements and cross-sectional types, as well as the road equipment. The institute is particularly suited to this area of research, using simulation techniques and a simulated driving simulator.
The area of transport and operation is concerned with organizational measures to improve traffic on roads. The most important areas of activity and research at the Institute of Highway Engineering in Aachen are:
Traffic data collection and analysis
Collection of traffic data for the description and analysis of the traffic flow
Use of micro simulation, eg for comparison of planning variants
Traffic control and safety
Optimization of traffic control systems with regard to:
Development of individual and collective traffic control
Development of forward-looking predictive procedures for road safety
Management of workplaces
Security and management procedures
Optimization of road equipment in the context of innovative signs, markings and protective devices
The Institute of Highway Engineering Aachen can look back on extensive experience in all of these areas. These includes both: the field of research and the field of application in practice.
The Chair and Institute of Highway Engineering has its research areas for underground transport facilities in the equipment, operation and control of road tunnels.
Safety aspects and environmental issues play a crucial role in this context.
In addition the Institute of Highway Engineering deals with questions of ventilation, video detection, fault management as well as the planning and design of tunnels.
