  • Effect of Cathodic Protection on EpoxyCoated Rebar
    Effect of Cathodic Protection on Epoxy-Coated Rebar
    Taylor, S. R. ;
    Bognaski, D. S.
    1998-06-01 | PDF
    Epoxy coating is widely used to mitigate the access of chloride ions to the surface of a rebar. However, corrosion at the point of physical defects in the coating necessitates rehabilitation. Based on its effectiveness in mitigating corrosion of uncoated rebars, we examined cathodic protection (CP) as a method for rehabilitating epoxy-coated rebars ...

    Demetsky, M. J.
    1998-06-01 | PDF
    This study had three goals: (1) To develop a method for reversing the planning process, such that we begin with transportation system usage and conclude with transportation system usage and conclude with an indication of land use; (2) To validate this process by calibrating the model with historical data and then using it to predict the present. To ...
  • Corrosion protection performance of corrosion inhibitors and epoxycoated reinforcing steel in a simulated concrete pore water solution

    1998-06-01 | PDF
    This report describes transportation planning data, available in numerous files and formats stored on the accompanying compact disc, that were compiled from planning studies for the Charlottesville/Albemarle area done in 1967, 1979, and 1990. These data were used for a Virginia Transportation Research Council (VTRC) report entitled "Measuring Trans ...
  • An asphalt paving tool for adverse conditions
    An asphalt paving tool for adverse conditions
    Chadbourn, Bruce A. ;
    Newcomb, David E.
    1998-06-01 | PDF
    Poor compaction can lead to early deterioration of an asphalt pavement. It often happens when paving occurs during adverse weather conditions. Yet, in Minnesota, paving must often occur under adverse conditions. A new tool now simulates the cooling of an asphalt mat behind the paver under a variety of environmental conditions. The software, PaveCoo ...
