Abstract
Stone Matrix Asphalt (SMA) is regularly and successfully used for surface courses in many countries. In this study SMA was designed using two different local aggregates blending ratios. The aggregate blends were tested for density, abrasion, crushing, water absorption and polishing before used in SMA design. Laboratory testing of the SMA surface mixtures was performed to determine volumetric and mixture specific characteristics. The results and analysis determined that SMA is a good surface meeting the design demands. All mixtures were tested for textural depth and skid resistance performance. It was concluded from this study that different aggregate blending can significantly alter the SMA mixture properties. The limestone and basalt blends can be successfully used to design an anti-slide SMA surface course.
