"What is asphalt?" you ask. Asphalt is the sustainable material for building pavements. It's smooth, so vehicles consume less fuel and produce lower emissions; it's quiet, so expensive noise walls don't need to be constructed; it's safe, providing excellent gripping power; and it's durable, so that the road never needs to be removed and replaced. It is also the most recycled material in the U.S.

Oh -- your question really was "What is asphalt made of?" Well, then! Asphalt is made from stones, sand, and gravel, held together by asphalt cement. View the video below to see what happens at an asphalt plant.
