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.

Road Construction Technology




Road construction

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

Surface properties:

  • 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

Road planning, road operation and road traffic engineering

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 acquisition and analysis

Traffic control and safety

Management of road construction sites

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.


Tunnel equipment and operation

The Institute of Highway Engineering Aachen has its research focus on underground transportation systems in the equipment, operation and control of road tunnels. Security and environmental issues play a crucial role in this context.

Research topics in this area include ventilation in normal operation and in case of fire, safety assessment and event management using operational and safety equipment.

For this purpose, the institute has self-developed video detection software (isacVITO) for automatic traffic data collection and event detection, which can be integrated into existing video surveillance systems.
