Why scientists are on a quest to make planet-saving pavement

Pavement may not seem complicated, but it is. Concrete is made of aggregate, tiny bits of sand, crushed stone, and gravel. Asphalt is composed of sand, gravel, and bitumen, a byproduct of oil petroleum production. Both can go into pavement. How much does just obtaining these materials tax the Earth? A lot. Fortunately, with the federal government purportedly inching toward a trillion dollar injection into American infrastructure, now may be the perfect time to make the gray stuff just a shade more green.
