According to the latest survey by the National Asphalt Pavement Association (NAPA) in partnership with the Federal Highway Administration (FHWA), more than 100 million tons of reclaimed asphalt pavement (RAP) was collected for re-use in the United States during 2018, saving nearly 61.4 million cubic yards of landfill space.
The average amount of reclaimed asphalt pavement (RAP) during 2018 was 21.1 percent, the highest level reported since the survey began in 2009. The survey found that 82.2 million tons of RAP, along with 1.05 million tons of recycled asphalt shingles (RAS) were used in 389.3 million tons of new asphalt pavement mixes in the United States during 2018.
An additional 8.8 million tons of RAP and RAS were used as aggregate, in cold-mix asphalt, and other road-building activities. The survey also found that at year-end 2018 about 111.7 million tons of RAP and RAS was stockpiled for future use.
Although national usable estimates were not calculated, survey respondents reported recycling some 1.8 million tons of recycled tire rubber, steel, and blast furnace slags, cellulose fiber, and other reclaimed and waste materials into nearly 12.3 million tons of asphalt during 2018.
