This report summarizes findings of a research study conducted to evaluate aggregate testing procedures as related to aggregate soundness and durability. The objectives of the study were to determine a suitable replacement or modification of Kentucky's existing Sodium Sulfate Soundness Test for aggregates which would more accurately reflect in-service performance of concrete pavements and bridges, to correlate freezing and thawing durability data and other test data with sodium sulfate soundness data, and to develop a rational implementation criterion for use of new or modified testing procedures.
There were no observable correlations between the various test methods evaluated and the Sodium Sulfate Soundness Test for aggregate types. Continued use of the soundness test, in strict accordance with Kentucky's Standard Test Method is recommended to evaluate aggregate soundness.
