Abstract:

The Alabama Department of Transportation (ALDOT) has more than 4.8 km (3 mi) of major Interstate bridges near downtown Birmingham with significant levels of deck cracking and deterioration. The bridges are part of the I-65 and I-59/20 Interstate highway system through the city and are approximately 30 years old. About 5 to 7 years ago, ALDOT bridge inspectors began to see longitudinal cracks in the top of the deck above the edges of the support girders. These cracks are continuing to grow in length and width and are beginning to combine with older transverse cracks to form surface spalls. ALDOT must make decisions on rehabilitation actions for the Birmingham decks in the near future. Toward this end, ALDOT is looking closely into what other states and highway agencies are doing, traffic demands and the need for additional lanes, the remaining fatigue and service life of the steel girder superstructures, punching shear load testing, delamination and deterioration of the existing decks, and placement of deck test sections using different rehabilitation strategies.
