Soil Compaction Handbook
Granular soils range in particle size from .003 to .08 (sand) and .08 to 1.0 (fine to medium gravel). Granular soils are known for their water-draining properties. Characteristics Sand and gravel obtain maximum density in either a fully dry or saturated state. Testing curves are relatively flat so density can be
