Bureau of ResearchUS Transportation CollectionThe report documents the performance of the decks based on crack surveys performed on the LC-HPC decks andmatching control bridge decks. The specifications for LC-HPC bridge decks, which cover aggregates, concrete,and construction procedures, as well as procedures for performing crack surveys, are summarized. The first 13LC-HPC bridge decks are compared to control decks in terms of crack density as a function of time. Survey resultsare also presented for three LC-HPC decks without control decks and one deck let under LC-HPC specificationson which the specifications were not enforced. The widths of measured cracks ranged from 0.006 to 0.025 inches(0.15 to 0.64 mm)
