In this TED talk, Erik Schlangen discusses a new form of porous asphalt formed from simple materials  that when cracked can be fixed using induction heating. This new material can potentially cut down on infrastructure costs, as paved roads made from traditional asphalt are much more expensive and difficult to repair. Schlangen hopes that his asphalt material will be put into widespread use in order to double the service life of roads.
