Conference on Stone-Matrix Asphalt

On November 5–7, 2018, the National Asphalt Pavement Association with support from the Federal Highway Administration will host the 1st International Conference on Stone Matrix Asphalt (SMA) in Atlanta, Georgia. SMA, also called stone mastic asphalt, was developed in Germany in the 1960s to provide heavily trafficked roads with a durable, rut-resistant wearing course using a gap-graded aggregate structure and a modified asphalt binder at elevated asphalt contents. SMA has been used worldwide for almost 50 years, and it has been used in the United States for the past 25 years, but only a handful of states have implemented it widely. Since its introduction to the U.S., SMA technology has evolved which may make it beneficial in broader applications. This conference will capture advancements made in SMA mixtures and pavements over the past 25 years.
