As it does not have sands or fine aggregates, it has less drying shrinkage compared to normal concrete

  • 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. Remove the finger from the opening and allow the sample to fall freely into
