Flax Fibers Revolutionize Asphalt Road Monitoring
Scientists at the Wilhelm-Klauditz-Institute (WKI) have created a revolutionary sensor system using flax fibers to monitor asphalt roads in real-time. Initial lab tests have shown promising results, and practical tests are now underway on a fully equipped road.
The innovative sensor mats, made of woven flax fibers with conductive wires, are produced using a double-gripper loom. They can withstand heavy installation loads, weathering, and general traffic due to their high durability and shift resistance.
The system works by measuring resistance changes in the sensor wires. Artificial intelligence then analyzes this data to detect and predict damages like cracks and holes in the asphalt layer. This eliminates the need for destructive core sampling.
A consortium led by Uhlig & Wehling GmbH Ingenieurgesellschaft, along with AS+BE Asphalt- and Betonstraßenbau GmbH, Time4Innovation UG, Fraunhofer WKI, Hochschule Magdeburg-Stendal, and Hochschule Hannover, are participating in the research project. The project is funded by the Federal Ministry of Transport.
The sensor data will be presented and visualized on an internet platform, benefiting authorities, residents, companies, road users, and other stakeholders. This groundbreaking technology promises improved road maintenance and enhanced safety for all.
