Toughness/abrasion resistance and durability/soundness tests for characterizing aggregate used in asphalt concrete were identified and evaluated, and those test methods that best correlate with field performance were determined. Based on a review of literature and specifications, laboratory tests for ...
The sulfate soundness test (ASTM C88) is widely used to gauge the resistance of concrete aggregates to damage by freezing and thawing. But, saturated Mg and Na sulfate solutions can dissolve limestones, introducing a bias that is not intended in the purpose of the method, which ...
On the average, 1/3 of the dolomite aggregate samples from northern Arkansas that are evaluated by the sodium sulfate soundness test exceed the 12% loss limit set by the Arkansas Highway and Transportation Department (AHTD) for acceptance. To aid in exploration for acceptable dolomite in this ...
