State departments of transportation are benefiting from new tools--like new research and lithium admixtures--now available to identify and fight destructive alkali-silica reactivity (ASR) in portland cement concrete roads and bridges. New guideline specifications released in late 1999 by an ASR Lead States Team may help states deal with ASR. Among other remedies, the model specifications state the lithium compounds are capable of suppressing deleterious ASR and provide guidance for lithium's use. The most widely available lithium-based admixture--LiNX lithium nitrate alkali-silica reactivity inhibitor--is proving its mettle in fighting ASR on a long-term basis. The synergy of new knowledge and new materials will accelerate the fight against ASR in coming years.
