Density of 3" crushed rock
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. Given a void ratio of 0.3 and a specific gravity of 2.7, the dry density would be: GammaD=0.7*62.4*2.7=118 pcf.

Acceptable Surfacing that meets ADA Standards
That being said, crushed rock--there is a distinction between the two materials--specified at 3/8" minus, with added fines, laid down in 2-3" lifts and well compacted, can be just fine for casual pedestrian use and should be ADA compliant. Decomposed granite is a great material to use, if well maintained. But also consider your …

Min Slopes on Gravel Parking lots
Gravel parking lots usually need a surface course of crushed aggregate, which includes some (usually ~8%) binder (read silt & clay). So it may not infiltrate water so well. And ofter other soil tracked in can lessen its infiltration capacity over time. Puddles may well infiltrate/dry out sooner than in pavement, but in the meantime damage is done.

self-compacting gravel? really?
The addition of fines will inhibit drainage so if this is a concern, don't do that. Additionally, a plate compactor is typically run over the pavers after you put the sand on them and that would be a heck of time to find out that the #57 stone could in fact be more densified. Run the plate compactor over the stone now while you have the chance.

Granular Fill/Gravel
Gravel may be natural or manmade and is usually round rather than angular ( although it may be either ). Granular fill is usually manmade crushed rock so it is almost always angular and may include some sand and even some small amount of silt sized particles. At least in my experience. Others may have a different view of this.

compaction for aggregate basecourse/sub-base?
Compacting to takes out most of the additional compaction that will be done by traffic. Not such a big deal with rigid pavement, but can be significant with flexible pavement.
