Stone mastic asphalt (SMA) is a hot mix asphalt consisting of two parts, a coarse aggregate skeleton and a binder rich mortar. It is made up of a mixture of crushed coarse and fine aggregates, mineral filler, asphalt cement, and a stabilizer for the binder such as polymer or fibers. The philosophy of SMA is that the coarse aggregate skeleton will provide a stone on stone contact (the stone portion) to prevent rutting and provide skid resistance and that the mix will be held together with sufficient specialized mortar (the mastic portion) to prevent draindown of the binder and provide the mix with durability. This report documents the Colorado Department of Transportation's (CDOT) first two SMA pavements. The first project is located in Boulder County on State Highway 119 and is documented in Section 2 of this report. The second project is located in Denver on Colfax Viaduct. This project was the first project placed on a bridge deck. This project is detailed in Section 3 of this report.
