Evaluation of Wearing Surface Systems for Orthotropic Steel-Plate Bridge Decks
Six wearing surface (WS) material systems were evaluated as potential replacements for the existing WS on the Poplar Street Bridge in St. Louis, Missouri. The materials were 2 asphaltic concretes, 3 epoxy concretes and a methyl-methycrylate concrete. Laboratory tests included flexural fatigue tests at 0 F and under cyclic temperature variations from 0 - 160 F. Concurrently, test sections of each material was placed on the bridge and monitored for 1-2 years. Recorded strains were correlated with the laboratory fatigue tests. One of the proprietary epoxy concretes was recommended, although none of them performed as well as desired.
