Stone Mastic Asphalt (SMA) - Hot Mix for High Stress Pavement Applications

Stone Mastic Asphalt (SMA) has been used successfully in Ontario since 1990. In the spring of 2002, south bound lanes of Huron Church Line (Highway 3) were constructed with SMA mix. Huron Church Line was suggested as having the most severe traffic in Canada and paving with asphalt was being questioned in Windsor on this roadway. The mandate on this project was to design and construct a superior performing hot mix pavement that would showcase asphalt pavement, as the surface of choice, and set an example for paving in high stress applications for all of Canada. This paper describes the practical experience in designing, production, and layout of SMA on this project. The mix was designed with Superpave gyratory compactor as per the American Association of State Highway and Transportation Officials specifications. The Asphalt Institute validated the mix design by testing the mix with the Asphalt Pavement Analyzer. The quality assurance testing results obtained, by both the Superpave gyratory and Marshall compaction methods, are reported. The pavement performance has been excellent to date and the future performance is being monitored. The successful experience on this project shows that SMA technology has been successfully developed and SMA is well suited to construct rut resistant pavements subjected to heavy traffic.
