Evaluation of the 4-Cycle Magnesium Sulfate Soundness Test
The report presents an evaluation of the 4-cycle magnesium sulfate soundness test to control quality of coarse aggregates for use in hot mix asphaltic concrete and seal coats. A total of 41 aggregates were tested for the purpose of this study in the laboratory and the behavior of eight of the aggregates was evaluated in the field by examining roadway performance. The soundness test was found to be the best method for predicting performance among specific gravity, absorption, aggregate durability index, freeze-thaw, Los Angeles abrasion, and modified Texas wet ball mill tests. Specific recommendations have been suggested to improve the soundness procedure. Specification limits for hot mix and seal coat projects have been included.
