14th Annual Asphalt Pavement Industry Survey on Recycled Materials and Warm-Mix Asphalt Usage
2023 Construction Season
The results of the asphalt pavement industry survey for the 2023 construction season show that asphalt mixture producers have a strong record of employing sustainable practices and continue to increase their use of recycled materials and warm-mix asphalt (WMA).
The objective of this survey, first conducted for the 2009 and 2010 construction seasons, was to quantify the use of recycled materials, primarily RAP and RAS, as well as the use of WMA technologies by the asphalt pavement industry.
Highlight features & benefits
- Reclaimed Asphalt Pavement: Asphalt mixture producers remain the country’s most diligent recyclers, with 89% of asphalt mixture reclaimed from old asphalt pavements being put back to use in new asphalt pavements and 11% being used in other civil engineering applications, such as unbound aggregate bases.
- Reclaimed Asphalt Shingles: Use of RAS increased 18%, replacing virgin materials with an estimated value of $109 million.
- Warm-Mix Asphalt Technologies: Mixtures produced with WMA technologies made up 39.1% of the total estimated asphalt mixture market in 2023.
“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 incorporation of recycled materials in pavement mixtures and the use of warm-mix asphalt (WMA) technologies.”
