AASHTO T 103 – Standard Method of Test for Soundness of Aggregates by Freezing and Thawing

This method describes three procedures to be followed in testing aggregates to determine their resistance to disintegration by freezing and thawing. It furnishes information helpful in judging the soundness of aggregates subjected to weathering, particularly when adequate information is not available from service records of the behavior of the aggregate.

The following applies to all specified limits in this standard: For the purpose of determining conformance with these specifications, an observed value or a calculated value shall be rounded off to “the nearest unit” in the last right-hand place of figures used in expressing the limiting value, in accordance with the rounding-off of R 11.
