Abstract:
Three methods of specifying the as built clear concrete cover depth include a minimum values, a minimum and maximum values with or without a pay item for the placing of additional concrete above the minimum cover depth, and a statistical based specification based on construction capabilities. Cover depths from 30 bridge decks built by three different contractors using minimum/maximum values and 21 bridge decks built by an unknown number of contractors under a minimum/maximum plus additional concrete pay item specifications are presented. Impact of these two cover depth specification methods on service life are presented.
