Abstract:

Ease of construction, favorable span-to-depth ratios, aesthetic appeal and high torsional stiffness make adjacent precast prestressed concrete box-beams a popular option for short-to-medium span bridges. However, persisting durability and performance issues resulting from longitudinal deck cracking at shear key locations threaten its favorability. Deck cracking is the primary trigger of deterioration and distresses of these bridges. The goal of this project was to develop practical recommendations for modifications to current details, specifications and methods used in the construction of adjacent precast prestressed concrete box-beam bridges in Wisconsin to minimize the potential for developing longitudinal deck cracking over shear keys.
