|Project Name:||Development of Nondestructive Evaluation Field Test Method for Alkali-Silica Reaction Detection and Identification of Cost-Effective Materials for Rehabilitation of Structures Affected|
|Start Date:||September 30, 2008|
|End Date:||June 5, 2013|
|Office:||Office of Infrastructure Research and Development|
|Team:||Infrastructure Management Team [HRDI-60]|
|Roadmap/Focus area(s):||Infrastructure Research and Technology Strategic Plan and Roadmap|
|Project Description:||This research study will identify/develop a combination of nondestructive and destructive methods to evaluate the present and future concrete deterioration for field concrete structures affected by alkali-silica reactivity (ASR). The research will also identify procedures and materials to rehabilitate concrete structures' deterioration due to the presence of ASR to extend their service life.|
The key project objectives are to:
(1) Develop nondestructive field test methods to evaluate concrete structures for presence of alkali-silica reactivity (ASR), estimate deterioration rate, and predict total expansion.
(2) Develop cost-effective methods to control alkali-silica reactivity (ASR) and extend the service life of existing highway structures.
