Abstract:
The article presents a forensic investigation of precast prestressed concrete piles removed from the I-95 Turtle River Bridge, near Brunswick, GA. The piles exhibited extensive damage that led to the discovery of unexpected threats to bridge substructures in marine environments. The results of the study emphasize the need to consider the presence of multiple modes of deterioration in concrete structures and their potential synergistic interaction.
