TED - Erik Schlangen: A "self-healing" asphalt

NUUG

Paved roads are nice to look at, but they’re easily damaged and costly to repair. Erik Schlangen demos a new type of porous asphalt made of simple materials with an astonishing feature: When cracked, it can be “healed” by induction heating. (Filmed at TEDxDelft.) TED talk downloaded from The Internet Archive.
