Figure 1: Fine aggregate specific gravity sample and pycnometer. The fine aggregate specific gravity test measures fine aggregate weight under three different sample conditions: Oven-dry (no water in sample). Saturated surface dry (water fills the aggregate pores). Submerged in water (underwater). Using these three weights and their relationships, a sample's apparent specific gravity, bulk ...

The weight of the sample depends on the maximum particle size of the material being inspected. As a rule, a larger top size material the larger the sample. A 25 lb sample of No. 2 coarse aggregate would not be as representative of the material as a 25 lb sample of natural sand. TWO IMPORTANT DEFINITIONS TO REMEMBER

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.
