Abstract : The evaluation included both theoretical analysis and field tests. The concrete, soil, and water were sampled and tested in the laboratory. Nondestructive tests were used to determine locations for coring concrete and to develop a condition profile for the structure. Load tests were conducted on the structure to determine deflections for comparison with analytical calculations. These comparisons show that deterioration has not reduced the structural capacity seriously at this time. Laboratory tests show the concrete to be severely deteriorated at some locations and sound at other locations only inches away. The concrete is severely cracked, corrosion of the reinforcement is occurring, and alkali-silica reaction is evident throughout the structure. The deterioration is expected to progress and accelerate as moisture migration to the interior of the concrete increases due to crack growth and further deterioration. The deteriorated condition of the existing track dictated a recommendation for replacement; therefore, a preliminary design for a new track was accomplished. The existing track should remain usable at current loading during construction of a new track.
