OBSERVATIONS and COMMENTS:
Scaling started on day 20. The sealer was rated on a scale of 0-5, with 0 being no scaling, 5 being severe scaling (coarse aggregate visible over the entire surface). The depth of the scaling on the rest panel was 1/16 inch. This is in the scale range of 0-1 because 1 allows scaling up to 1/8 of an inch. Therefore, a rating of 1 was selected for the test panels.
CONCLUSIONS:
1. The sealer was rated 1, on a scale of 0-5, for the Freeze/Thaw test. 0 being no scaling, 5 being severe scaling (coarse aggregate visible over entire surface)
