ROAD WARRIOR MAKING BLACKTOP OUTOF PIG POOP

asphalt is tricky stuff. Essentially the leftover goo from oil processing, it contains almost 100,000 different molecules. Not even materials engineers know what they all are—or how a given batch of blacktop might react to stressors like moisture or cold. It's also pricey. But civil engineer Ellie H. Fini (above) and her collaborators at North Carolina A&T State University have a solution to tarmac's shortcomings: pig poop.
