The asphalt pavement industry has a long history of incorporating reclaimed asphalt pavement (RAP) and other recycled materials – including recycled tire rubber, slags, recycled asphalt shingles (RAS), glass, and even pig manure -- right back into the mix, creating a strong foundation for a circular economy.
NAPA, in partnership with the Federal Highway Administration (FHWA), quantifies the use of these technologies through an annual survey. The full report and related materials, including a state-by-state breakdown of recycled materials usage, can be downloaded below:
