Project description

The objectives of this research effort include: (1) providing a review of current technology and “best practices” for extending the service of alkali–silica reaction (ASR)-affected concrete, (2) developing approaches for assessing condition state in potentially ASR-affected concrete and determining potential for further reaction and damage, and (3) developing combined material and structural repair strategies to extend the service life of ASR-affected concrete. The effective assessment and repair techniques for extending the service life of ASR-affected concrete, will be presented in Georgia Department of Transportation (GDOT) Specification/Special Provision format.
