Fate in Recycling

Asphalt pavement remains among the most heavily recycled materials in the US. Emerging concerns associated with PFAS contamination to asphalt pavements exposed to firefighting foams at military installations, airports, and fire-training facilities has raised questions regarding the fate of PFAS within common asphalt recycling practices. Utilizing field-collected and laboratory-generated pavements, we are working to examine PFAS leachability, volatility, and behavior through the various lifecycle stages of recycled asphalt pavements.
