Abstract:This technical assistance report documents the investigation conducted by the Louisiana Transportation Research Center (LTRC) of the cored concrete from Westbound Jefferson Highway near Airline Highway in Baton Rouge, LA. The petrographic analysis showed that the cause of cracking was primarily due to Alkali-Carbonate Reaction (ACR). Possible remedies for this section include continued patching efforts and full-depth replacement of the section since ACR cannot be mitigated with an overlay.
