• Abstract:
  Twenty-one, four-inch cores were taken from seven locations on the bridge deck. Each core was subjected to visual and low magnification examination, load deformation determinations and impact hammer readings. Thin sections were made from cores from each location and studied under the petrographic microscope. Some of the larger pieces of aggregate were removed from the cores and subjected to differential thermal analysis. To supplement information obtained from the cores, laboratory specimens were cast from three concrete mixes using lightweight aggregate from the same source as that used in the bridge deck but manufactured 11 years later. Two of these mixes were made to conform as closely as possible to the mix design used in the bridge deck.
