Alkali-Silica Reaction in Concrete Pavements at Atlanta's Hartsfield-Jackson International Airport — A Case Study
The network of runways, taxiways and aprons at Hartsfield-Jackson Atlanta International Airport (H-JAIA) mostly consists of aging concrete pavements. Some of these pavements are undergoing materials-related distress, in particular alkali-silica reaction (ASR). With over 37.5 million square feet of structural concrete pavement, durability and useful service life of concrete is critical for efficient operations at one of the busiest airports in the world. The evaluation of extent of ASR has been part of a periodic network-level pavement assessment program at H-JAIA. One runway and parts of two parallel taxiways were reconstructed, and another runway is scheduled for reconstruction 2006, primarily due to deterioration resulting from ASR. This case study presents the results from a recent investigation conducted at H-JAIA on one of the distressed runways. Results from this study present evidence of extensive ASR induced damage in concrete pavements at H-JAIA. In addition a discussion of potential factors that may have caused the ASR distress at H-JAIA is presented.
