| Project detail | ||
| 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. | |
| Goals: |
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.
