Erik Schlangen Proves the Potential of “Self-Healing Asphalt”

Imagine a pervious asphalt that not only significantly reduces noise pollution, but saves millions in maintenance and repairs by its ability to self-heal. Well, this type of super-asphalt is not far from being distributed world-wide as experimental micromechanic pioneer Erik Schlangen of Delft Technical University has been studying the material’s potential on a test track in The Netherland’s for the past few years.

Basically, with the introduction of small steel wool fibers, Self Healing Asphalt is capable of repairing micro-cracks and significantly extending the service life of roadways through induction heating. Similarly, Schlangen is leading the research on Self Healing Concrete, where by infusing concrete with a harmless limestone-producing bacteria that feeds off of calcium lactate - a component of milk - the material has the potential to self-heal micro-cracks in the presence of rainwater.
