FHWA Division Office Survey on State Highway Agency Usage of Reclaimed Asphalt Shingles: Quantities, Trends, Requirements, and Direction - Results from May 2017 
Primary Topic: Pavement Recycling
Description: In recent years, the economics and supply of petroleum and high quality natural aggregates have increased the need for cost-effective alternatives to virgin paving materials. The use of reclaimed asphalt pavement (RAP) and reclaimed asphalt shingles (RAS) in the asphalt mixture is increasing because they provide initial cost and material resource benefits. However, they create new challenges for state highway agencies (SHAs) to specify and control the quality of asphalt mixtures for long-term pavement performance.
