By 2060, the German government will have invested more than €260 billion in roads, waterways and the rail network. The majority of this will be used for the renovation of existing transport routes. At the moment it is still very expensive to establish repair requirements. In various projects, BAM is researching the use of wireless sensors, which will be able to help identify damage to the concrete of traffic structures more quickly, efficiently and cost-effectively in the future.

Non-destructive testing methods for safe construction

The safety of infrastructure construction is one of BAM's central topics of research. In the area of structural safety, there is a particular focus on assessing heavy loads, fire and explosion scenarios, and on developing new safety concepts. BAM has decades of experience in this area. Testing methods and intelligent monitoring systems that are embedded in structures help us to better gauge the durability and operational lifespan of infrastructure facilities. Non-destructive testing processes are particularly valuable here. They can be used, for example, to evaluate the structural condition of bridges.

Focus on the safety and load-carrying capacity of bridges

Time and again, dilapidated bridges in Germany make headlines. There are around 39,500 bridges in the motorway network alone, which must be continually monitored and maintained to ensure their safety. Once damage occurs, renovations are much more expensive and time-consuming. In this field, BAM is researching, for example, innovative processes for assessing the durability of bridges, in order to determine how the load-carrying capacity of bridges that are 40 to 50 years old can continue to be guaranteed. Sensors are used here as well to capture details of the shocks, vibrations and loads with an impact on the reinforced concrete. As a result, damage can be promptly identified and repaired.
