There are about 2.8 million miles of roads in the United States, and 94% of that is made of asphalt. There's also recycled asphalt pavement, which is exactly what it sounds like: pavement that has been scraped off a road, ground up and used again. Right now, CRH says about 25% of every mile of road it paves is recycled asphalt pavement, though there are some places where the share of recycled asphalt is much higher. The reason: When recycled pavement was first introduced, it had a tendency to degrade faster, simply because it was older. The industry, represented by the National Asphalt Pavement Association, wants to raise the level of recycled asphalt in any given road to about 50% of the mix that is laid down.
