For example, Michigan DOT specifies requirements for fine aggregates used in HMA and surface treatments. For slurry seals, Michigan DOT requires using a fine aggregate material complying to their 2FA gradation band. The fines can consist of crushed material, gravel, slag, or a blend and must have LAA loss not exceeding 45%.

Fine aggregate should fall within gradation limits provided in ASTM C 33, Section 6. If there is a deficiency in a locally available fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material (SCM) to address these shortcomings.

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. The FAA test estimates fine aggregate angularity by measuring the loose uncompacted void content of a fine aggregate sample.
