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.)

Re: Ted Talks: Erik Schlangen: A "Self-Healing" Asphalt
It's a nice idea with some very interesting applications. That said, if you need to go over it with a large induction heater, it isn't really "self-healing" But the speaker also doesn't talk about the affect of freezing. In a Midwest climate I suspect that the constant freezing and thawing would have that surface reduced to rubble in weeks.
