Project ID:FHWA-PROJ-08-0041
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
Status: Completed

Last Name:Virmani
First Name:Paul
Telephone:202-493-3052
E-mail:paul.virmani@dot.gov
Office: Office of Infrastructure Research and Development
Team:Infrastructure Management Team
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.
Start Date: September 30, 2008
End Date: June 5, 2013
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. 
Test Methodology: Materials and methods for rehabilitation and nondestructive evaluation (NDE) techniques.
Expected Benefits:The expected benefits are better materials and quicker alkali-silica reactivity detection methods.
