• Abstract:
  Roadways that are both durable and aesthetically pleasing are primary goals of Wisconsin ; Department of Transportation (WisDOT) paving projects. Recently, Portland Cement Concrete ; (PCC) pavement projects constructed by WisDOT have experienced increased amounts of ; scaling within the first two years of service life. Scaling is a form of surface damage that can lead to ; decreases in the aesthetic appeal, functionality and service life of a PCC pavement. Scaled pavements ; typically demonstrate symptoms including surface roughness, exposed aggregates, collection of ; loose scaled material on the surface and discontinuities in both the outward appearance and level of ; the top layer of the pavement. Membrane-forming curing compounds (MFCCs) are used in paving ; applications to properly ensure that the mix water within the mortar that comprises the top ¼ to ½ ; inch of the concrete pavement surface does not prematurely evaporate and inhibit hydration. However, ; pavement projects using any one of several different WisDOT-approved curing compounds still ; experienced scaling within a few years of construction.
