Nearly 39 percent of asphalt pavement mixture produced in 2017 was produced as warm-mix asphalt at reduced temperatures—a 777 percent increase since 2009—which decreases energy demands, reduces air emissions and improves compaction at cooler temperatures, according to a study by the National Asphalt Pavement Association in partnership with the Federal Highway Administration. Additionally, more than 99 percent of the asphalt pavement material removed from roads and parking lots last year was put back to productive use, primarily in new asphalt pavement mixtures.

The also survey found that more than 76.2 million tons of reclaimed asphalt pavement and nearly 950,000 tons of reclaimed asphalt shingles were used in new asphalt pavement mixes in the United States during 2017. An additional 3.9 million tons of RAP and RAS were used as aggregate, in cold-mix asphalt and in other road-building activities. Reclaiming RAP for use in future pavements saved nearly 50 million cubic yards of landfill space last year.
