Project description

The purpose of this study is to investigate the feasibility of using the newly developed Turner-Fairbank Highway Research Center ASR Susceptibility Test (T-FAST) for aggregate acceptance on the Approved Materials List (AML). Results from Turner-Fairbank Highway Research Center showed T-FAST could produce accurate alkali-silica reaction (ASR) aggregate testing in as little as 21-days of age. Therefore, T-FAST may be very beneficial for the Louisiana Department of Transportation and Development (DOTD) to produce aggregate acceptance results in a short time frame.
