SOUTH DAKOTA PROJECT SUCCEEDS WITH SMA

This article describes the successful application of Stone Matrix Asphalt (SMA) in a pavement reconstruction project on I-29 by the South Dakota Department of Transportation (DOT). The SMA mix, chosen partly for its high rut-resistance, was the first time an SMA mix was used in the state. The mix that was selected involved local quartzite aggregate which provided good surface friction, and cellulose and fly ash fibers to prevent binder drain down. The article details how a 12.5-mm wearing course was laid over the existing asphalt overlay.
