Revolutionary Flax Fiber Sensor System Monitors Roads in Real-Time
Scientists at the Wilhelm-Klauditz-Institute (WKI) have created a revolutionary sensor system using flax fibers to monitor asphalt roads in real-time. This innovative technology can detect damages like cracks and holes without destructive sampling, and it's currently being tested on a road in an industrial area.
The sensor mat, woven with 1 mm thick conductive sensor wires, can withstand heavy loads during installation and from weather and traffic later on. Initial lab tests have been successful, and practical tests are now underway. This research project is funded by the Federal Ministry of Transport and involves several other participants.
The sensor system can precisely record axle loads as vehicles pass by, indicating its potential for accurate damage detection. It can even predict future damages, allowing for early maintenance and repair by road authorities and builders. Damages in the asphalt layer cause resistance changes in the sensor wires, which are measured and analyzed using AI-based software. The data will be presented and visualized on an internet platform for authorities, residents, and other affected persons.
The WKI's innovative sensor system, developed with support from Fraunhofer and its partners, promises to revolutionize road maintenance. By enabling real-time monitoring and predictive damage detection, it could significantly improve road safety and reduce maintenance costs.
