14th Annual Asphalt Pavement Industry Survey on Recycled Materials and Warm-Mix Asphalt Usage

A shared goal of the Federal Highway Administration (FHWA) and the National Asphalt Pavement Association (NAPA) is to support and promote sustainable practices, such as incorporating recycled materials in pavement mixtures and the use of warm-mix asphalt (WMA). This report documents the results of the industry survey for the 2016 construction season, including the survey methodology, results, trends, and changes from 2009 through 202.

Highlight features & benefits

• Reclaimed Asphalt Pavement: The total estimated tons of RAP used in asphalt mixtures was 96.1 million tons in 2023. This represents a 71.6 percent increase from the total estimated tons of RAP used in 2009. Since 2009, total asphalt mixture tonnage has increased by only 22.7 percent.
  Reclaimed Asphalt Shingles: The total estimated tons of RAS used in asphalt mixtures increased 18 percent to an estimated 797,000 tons in 2023. The increase in the use of RAS reported during the 2023 construction season still leaves utilization at about 59 percent below the 2014 peak level of reported usage.
• Warm-Mix Asphalt Technologies: The estimated total tonnage of asphalt pavement mixtures produced with WMA technologies for the 2023 construction season was 172.0 million tons. This was a 1.7 percent decrease from the estimated 175.0 million tons of WMA in 2022, led by decreased WMA tonnage in the Other Agency and Commercial & Residential sectors.
