• 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.
