Abstract: The raising of a continuous span reinforced concrete (RC) bridge creates the potential for subjecting the bridge to loading deformations for which it was not designed. This, coupled with the inherent weakness of concrete ...

Abstract: The Alabama Department of Transportation (ALDOT) employs thinner decks on their highway bridges than almost all other states and countries, and unfortunately many of these decks are exhibiting significant levels of cracking ...

Abstract: Due to road resurfacing a significant number of highway bridges throughout the nation violate underneath clearance requirements. A bridge lifting/monitoring system was developed as one solution to this problem. The system ...

Abstract: The Alabama Department of Transportation (ALDOT) currently maintains over three miles of interstate bridges near downtown Birmingham with significant levels of deck cracking and deterioration. The rehabilitation of these ...

Abstract: This article reports on the results of two actions that were taken to assess the nature, extent, and primary causes of highway bridge deterioration in Alabama. The first was a mail survey questionnaire that was sent to all ...

Abstract: Bridge deck rehabilitation via overlaying has been widely used in the colder regions of the United States but not in Alabama due to a warmer climate and nonuse of deicing salts on bridge decks. However, Alabama does have ...

Abstract: Plastic shrinkage cracking of concrete bridge decks occurs when the water evaporation rate at the surface exceeds the bleeding rate of the freshly placed concrete. Also, the rate of early drying shrinkage after the concrete ...

Abstract: A companion paper reported on theoretical considerations associated with adding girder lines to rehabilitate highway bridge decks and superstructures. This article reports on practical, construction, and cost considerations ...

Abstract: To gain a better understanding of how highway bridges in Alabama are performing in the area of durability/longevity, a review of the historical bridge records of the Alabama Department of Transportation was performed. ...

Abstract: About two years ago, the Alabama Department of Transportation (ALDOT) increased its minimum bridge deck thickness to 178 mm (7 in.), and thus ALDOT’s deck thicknesses now range from 178 to 197 mm (7–7.75 in.). Even with ...
