Temperature-dependent performance of polymer concrete wearing surface system on the Poplar Street Bridge. Final report
The report details a five-year study of the performance of the epoxy (polymer) concrete wearing surface placed on the orthotropic steel-plate deck of the Poplar Street Bridge in St. Louis, Missouri. This study involved inspections, field testing and laboratory experiments and analyses. During the first few years, the focus was on the field study components. Later when some cracks were observed on the wearing surface, a detailed experimental and analytical investigation was incorporated to understand the cause of the cracks and study potential crack-repair procedures. Laboratory experiments were undertaken to study the temperature-dependent mechanical properties of the polymer concrete materials used on the bridge deck. Experiments included a series of static flexural tests, axial compression tests and flexural fatigue tests on the polymer concrete specimens under three different test temperatures. Temperature-dependent mechanical properties such as modulus of elasticity and fatigue strength were obtained from the tests.
