The use of recycled materials in asphalt mixtures – and on the roads we drive – is continuing to rise, according to a recent survey by the National Asphalt Pavement Association. Reclaimed asphalt pavement and recycled asphalt shingles (RAS) are resulting in economic savings and are sustainable. However, many transportation agencies are still reluctant to allow high contents of recycled materials in asphalt mixtures because of potential construction and performance issues. Auburn’s National Center for Asphalt Technology (NCAT) is taking a leading role in addressing these issues. Through laboratory and field experiments at NCAT’s Pavement Test Track, researchers are evaluating state-of-the-art methods for using large amounts of recycled materials in asphalt pavement design while also improving long-term performance. It’s just another way Auburn Engineering is conducting research that makes an impact.
