Objectives of the Study:
1) Establish the basis for Mn/DOT'S current quality specifications/tests for concrete aggregate.

predict aggregate freeze-thaw durability in PCC pavements.
3) State Author's opinions of best test(s) for the laboratory determination of aggregate freeze-thawdurability for use in Minnesota.
