Recycled Roadways | FHWA

The United States produces 1.8 billion metric tons (2 billion tons) of aggregate annually. In response to increased demand, aggregate production is expected to increase to 2.3 billion metric tons (2.5 billion tons) by the year 2020—a statistic that raises concerns about the pace at which aggregate is being consumed.
