Funding for the Federal Highway Administration (FHWA) Alkali-Silica Reactivity (ASR) Development and Deployment Program was provided under SAFETEA-LU. A related Conference Report provides additional guidance stating that "project and programs related to ASR should...assist states in inventorying existing structures for ASR." Throughout the program, the FHWA has been leading a national effort to further the development and deployment of techniques which can prevent and mitigate ASR.
