Cement Concrete Non-Alkali Silica Reactive Aggregate Sources

Sources on this list were qualified as of the date posted: August 31, 2026

MassDOT reserves the right to remove aggregate sources from this list if future ASR test results show ASR reactivity.  MassDOT will be conducting ASR verification testing of mitigated concrete mixes submitted by ready-mix and precast/prestressed producers throughout the year.  If test results are out of specification limits, the Producer will be notified immediately and the mix designs utilizing those materials will be disapproved.  If additional SCM content is required to prevent ASR, the mix design shall be reformulated and resubmitted by the Producer for review and approval.
