  • Density of 3" crushed rock - Earthwork/grading engineering ...

    Jul 01, 2008 · For me crushed rock is pretty well-graded and there'd be plenty of finer grains to infill the voids of the larger aggregate. Bear in mind coarser soils have a lower void ratio than finer soils. So, just because you can see the voids of a large aggregate material, does not mean the void ratio is greater than a fine grained soil.
