Using recycled asphalt shingles in hot mix asphalt (HMA) has been a developing technology for more than two decades with growing acceptance by both construction contractors and government agencies. With the recent spike in asphalt and cement prices, there is increasing pressure to find such acceptable recycled supplements to virgin materials. The state of Minnesota has sponsored several research studies on the use of recycled shingles in HMA over the past 15 years. This paper describes a recent study that investigated the use of both tear-off shingle and manufacturer shingle combined with traditional reclaimed asphalt pavement materials. A parallel study performed in Missouri is also included in the investigation.
