Self-healing Concrete Vanishes Potholes Using Bacteria. Here's How it Works

Potholes be gone! A new cement being developed in the U.K. can potentially make those annoying, and sometimes dangerous, road hazards a thing of the past.

The researchers from three British universities are calling it a self-healing concrete, and it could revolutionize how streets are paved and help the environment at the same time.

The concrete blend will be rich in a special kind of bacteria that lay dormant and hidden in tiny capsules. As soon as the mixture gets wet, like from rainfall which causes gaps to form, widen and eventually turn into potholes, the bacteria spring into action by forming limestone to fill in the air spaces.
