That Black Stuff on the Road? Technically Not Asphalt

Apr 27,  · When you hear the word asphalt, you probably imagine the black tar stuff on roads and highways, right? But that's not exactly correct. "Asphalt is the liquid that is in the road," says J. Richard Willis, Ph.D., vice president for engineering, research and technology at the National Asphalt Pavement Association (NAPA), who has a doctorate in asphalt design and construction.
