13th 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 2022.

Highlight features & benefits

• Reclaimed Asphalt Pavement: The total estimated tons of RAP used in asphalt mixtures was 98.1 million tons in 2022. This represents a
  75.2 percent increase from the total estimated tons of RAP used in 2009. Since 2009, total asphalt mixture
  tonnage has increased by only 23.3 percent
  Reclaimed Asphalt Shingles: The total estimated tons of RAS used in asphalt mixtures increased 7 percent to an estimated 673,000 tons in 2022. The slight increase in the use of RAS reported during the 2022 construction season still leaves utilization at about 65 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 2022 construction season was 175.0 million tons. This was a 1.6 percent decrease from the estimated 177.9 million tons of WMA in 2021, led by decreased WMA tonnage in the Commercial & Residential sector.
