Alkali-Silica Reactivity (ASR) Development and Deployment Program

Field Trials and Demonstration Projects

Field trials are necessary to gather long-term data on the effectiveness of methods and techniques to prevent ASR in new concrete and mitigate ASR in existing concrete. Field trails and continuous monitoring will be beneficial to gain information on the service life of mitigation methods. Information obtained in the laboratory needs to be applied to demonstration and field projects to obtain real life data.

Demonstration Projects are an effective way to gather where surrounding States at a project site to see first-hand mitigation and/or prevention techniques. This method has been found to be favorable with personnel from State agencies.

A comprehensive approach to field application and demonstration projects will be developed and implemented. The approach will include a plan to select field projects, full implementation of the project include appropriate selection of mitigation or prevention method, evaluation of the project including analysis of data, and using the project data and results to build upon methods evaluated.

Funding will be available to States for field trial and demonstration projects. If you are interested in an ASR project in your State contact Gina Ahlstrom for more information.
