Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
Ideally, crusher run gravel is compacted to 95% of its maximum dry density as measured by the Standard Proctor test. Anything less can severely reduce its strength as a sub-base material. This is why construction experts stress the mantra of compact, compact, compact when working with gravel.
Proctor Test (ASTM D1557-91) The Proctor, or Modified Proctor Test, determines the maximum density of a soil needed for a specific job site. The test first determines the …
Ron is right in that a lot depends on the material. For a well graded crushed sand and gravel (road base) I've seen as much as 400 kPa used (assuming that there is no underlying softer material within the zone of influence). We've compacted residual clayey silt to silty clay at 95% standard Proctor and obtained an effective friction angle of 32deg.

Penetrations vs. load values are plotted on a graph and corrected following the procedure specified in the test standard. Corrected stress values from penetration depths of 0.100 and 0.200in (2.54 and 5.08mm) are divided by standard stresses of 1,000psi (6.9mPa) and 1,500psi (10.3mPa), then multiplied by 100.

The standard and modified Proctor tests are conducted in a similar manner. For the modified Proctor compaction test, the Proctor hammer is heavier — 10 pounds instead of 5.5 pounds — and is dropped from a greater height — 18 inches instead of 12. The result will be lower optimum moisture content and higher maximum density for the soil.
ABC gravel typically contains stone that is no larger than 1 to 1.5 inches. Larger stone (3-inch) has more strength to support heavy logging equipment. ABC and 3-inch crusher run gravel contain a high percentage of fines (gravel dust) that add no more strength to a road than the soil beneath it. In some applications though, the fines may help ...
Test procedures are similar, but the laboratory compactive effort of the modified method is higher. Using a 10lb (4.54kg) hammer with 18in (457.2mm) free-fall instead of the 5.5lb (2.49kg) hammer with 12in (304.9mm) drop. This results in higher maximum soil densities at lower optimum …
Crusher-run gravel compacts well but does not drain very fast -- at least not as fast as 3/4-inch crushed stone (no fines). Talk to a soils engineer if you are worried -- but in my experience, either crusher-run gravel (compacted) or 3/4-inch crushed stone can be used under footings. So can rigid . An engineer may disagree.

Gravel and sand compacts best with a drum roller or a vibrating plate compactor. "We use an 8-ton rubber-wheeled drum roller," says Lloyd, "and compact to 98%--both the subgrade and the subbase. When we're done it's almost like concrete. When the laser screed or ready-mix trucks drive across it they won't even leave tracks.
