Abstract: An evaluation is made of bridge deck survey findings and laboratory research data in order to characterize the most common types of bridge deck deterioration. Possible causes are identified from the findings of published bridge deck surveys. The most widely accepted mechanisms of deterioration and related results of research on concrete fracture are described. The thermal incommpatibility mechanism and structural cracking mechanism are introduced to explain certain laboratory tests results and observed bridge deck deterioration. The use of revibration, nonrusting reinforcement; polymerized concrete, mixes with improved resistance to early cracking, and the adoption of improved methods of mixture quality control and aggregate selection are suggested as possible preventatives.
