The National Asphalt Pavement Association (NAPA) is encouraging every asphalt mix producer in the U.S. to participate in its latest survey on the use of recycled materials and warm-mix asphalt. The confidential survey is conducted by NAPA under contract with the Federal Highway Administration (FHWA) each year to document the volume of recycled materials used in new roads.

"In 2018, data from more than 1,300 asphalt plants were included in the survey, ensuring a high level of reliability for its findings. Greater industry participation in the survey helps ensure the industry’s environmental impacts are properly understood by federal and state agencies, as well as the public," NAPA Director of Engineering and Technical Support Brett Williams, who is administering the survey, says.

Since 2009, this survey has confirmed that asphalt pavement mixtures are the most recycled material in the U.S., with nearly 100 percent of the material removed from old roads and parking lots being reclaimed for use in new pavements. The survey has been cited more than 350 times in academic literature and is used by FHWA, the Department of Energy and other public agencies to measure the impact of these technologies.

Responses are sought from producers of all sizes and from every community in all 50 U.S. states, as well as all U.S. territories. Additional information is also being sought about the use of in-place recycling technologies during 2019.

For the 2019 construction season, FHWA asked NAPA to expand the survey collection effort to include in-place recycling techniques, including cold-in-place, hot-in-place, cold central plant recycling, and full-depth reclamation. Companies using these technologies are also encouraged to participate in a short supplementary survey at
