Yellowstone is a national park that is over 3,000 square miles and is home to many animals, geysers, and mountains. The eco-system is very delicate at Yellowstone and they want to make sure to preserve it. The cycling of water is an important aspect to this eco-system and in order to maintain that they have developed a new concrete. The "thirsty" concrete, called Flexi-pave, can absorb around 50 gallons of water per minute! On top of that, the mix is composed of recycled tires as well as other materials.
