Evaluation Of Procedures For Testing Aggregates, David Q. Hunsucker

Kentucky Transportation Center Research Report

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 …
