Durability and Soundness - Pavement Interactive

Overview. The soundness test determines an aggregate 's resistance to disintegration by weathering and, in particular, freeze-thaw cycles. Aggregates that are durable (resistant to weathering) are less likely to degrade in the field and cause premature HMA pavement distress and potentially, failure.. The soundness test repeatedly submerges an aggregate sample in a sodium sulfate or magnesium ...

Fine Aggregate Angularity - Pavement Interactive

The fine aggregate angularity (FAA) test (Figure 1) is an indirect method of assessing the angularity of fine aggregate. Fine aggregate angularity is important because an excess of rounded fine aggregate (often in the form of natural sand) can lead to HMA rutting. Figure 1: Fine aggregate angularity test.
