Aggregate bulk specific gravity may be one of the least appreciated factors affecting the performance of asphalt pavements. Although high quality mixtures can be made with aggregates having a wide range in bulk specific gravity values, precisely determining the bulk specific gravity (Gsb) is critical to setting the optimum asphalt content of every …
The specific gravity may be expressed as bulk specific gravity or apparent specific gravity. Bulk specific gravity and absorption are based on a 24 ± 4-h soaking time for the rock specimens tested. This test is appropriate for breakwater stone, armor stone, riprap, and gabion sized rock materials.

ASTM C97/C97M – Absorption and Bulk Specific Gravity of Dimension Stone: This test measures the water absorption and bulk specific gravity of dimension stone. It helps determine the stone's porosity and potential resistance to staining, weathering, and freeze-thaw cycles.
What is the difference between bulk specific gravity and specific gravity? Bulk specific gravity and specific gravity measure weight per unit volume differently. Bulk density measures partially compacted material, while specific gravity measures fully compacted material. The inclusion or exclusion of pores causes this difference.
