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 reports include state-by-state breakdowns of recycled materials usage.

94.6 Million Tons The amount of reclaimed asphalt pavement (RAP) recycled into new mixes in 2021—an 8.74% increase over the previous year

95% The percentage of asphalt mixture reclaimed from old asphalt pavements and put back to use in new pavements in 2021—up from 93% the previous year

630,000 Tons The amount of recycled asphalt shingles (RAS) put to use into asphalt mixes in 2021—up 8% from the previous year

26 Million Barrels The amount of virgin asphalt binder that was replaced by recycled binder from RAP and RAS in 2021—up 2 million barrels from the previous year
