PCCP roundabout with polymer overlay

MDT uses polymer overlays on our bridge decks as a protective and safety measure. These polymer overlays consist of using epoxy to secure a fine aggregate to the surface of the concrete deck on the bridge. This protects the surface of the bridge as well as adds a textured surface to aid in vehicle traction. With this project, MDT will evaluate the performance of a polymer overlay on PCCP (portland cement concrete pavement). The selected project is the Dern/Spring Creek intersection on US Highway 2 just west of Kalispell. The four-way intersection will be replaced by a concrete roundabout and the PCCP used for the roundabout will be finished with a polymer overlay. The hopes of this evaluation is that the polymer overlay will provide the same benefits to the PCCP as seen on bridge decks.
