AASHTO Innovative Highway Technologies Alkali-Silica Reactivity
Lead States Team

From 1995 to 2000, the members of the Lead States Team for ASR, with the assistance of partners from universities, industry, and the Federal Highway Administration, was engaged in several projects to accomplish its goals of increasing awareness of ASR; developing guidelines and encouraging use of technologies for treating and preventing ASR; and completing research projects begun under the Strategic Highway Research Program. These projects included testing new in-service pavements to determine which concrete mixes and additives prevent ASR-related damage and developing a new, environmentally safe screening test for ASR in existing concrete.

The following documents were developed by the team at the Lead States Workshops:
