Fine Aggregate Angularity | Pavement Interactive

Overview. 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. The FAA.

Effects of Aggregate Angularity on Mix Design Characteristics and .

Of the various tests for measuring aggregate angularity, the current Superpave mix design method uses the standard “number of fractured faces” testing method (ASTM D5821) for coarse aggregates and the “uncompacted void content” method for fine aggregates (AASHTO T304). National Cooperative Highway Research.

UNCOMPACTED VOID CONTENT OF FINE AGGREGATE

on the particle shape and texture of a fine aggregate. An increase in void content by these procedures indicates greater angularity, less sphericity, rougher surface texture, or some combination of these three factors. Method C measures the uncompacted void content of the minus No. 4 portion of the as-received material.
