March 15, 2013 - Engineering professor Erik Schlangen, of Delft University of Technology, may have found a way to double the expected lifespan of asphalt. He did this by inventing a "self-healing" asphalt material. Asphalt is used for many roads becuase of its noise reduction and water drainage capabilities, but begins to show signs of wear after a few years.
Click on the link below to watch the video of Schlangen using heat induction (in this case a microwave) to mend a 2 broken pieces of asphalt together into 1. It is also claimed that the new "healed" asphalt is stronger then the original asphalt. The asphalt is infused with pieces of material similar to steel wool. The cost of the new asphalt would go up roughly 25%, but would be worth the investment if it lasts twice as long!
