Fine Aggregate Angularity Pavement InteractiveOverview. 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 .
