Federal Highway Research Institute in Germany is currently testing self-healing roads on parts of the autobahn using mineral capsules embedded in concrete.
When rainwater enters microcracks, it dissolves these capsules, releasing compounds—like limestone-producing bacteria or reactive chemicals—that seal the cracks from within .
Significant Potential Benefits:
Early reports indicate this method can reduce repair costs by over 40% and greatly extend the lifespan of road surfaces .
Still in Pilot Phase:
Despite the buzz, these roads are not yet widely implemented nationwide in Germany. The technology is in field-testing and small-scale demonstration phases, not full deployment
