What Is The Best Gravel For Compaction
If you are compacting road crush with a vibratory plate you will get about 10 to 15% compaction. (This is based on you having a stable compacted base first. If you are putting the road crush on top of top soil you will lose more to compaction.) If you use a jumping jack, about 20% would be accurate.

Powder Compaction Process
As the forming process in powder compaction problems is a large deformation process, an elasto plastic analysis often utilizes a large strain model. However, in many forming processes where displacement are large, this is not sufficient and must be coupled with an updating of the calculation region mapped by the elements. The Lagrangian description can be applied to describe the material

Plate Load Test – Technical Standards for Anix AX01
On gravel and crushed stone base courses, the ratio of the deformation moduli Ev2/Ev1 must not be greater than 2.2 if a degree of compaction DPr ≥ 103 % is stipulated. With a degree of compaction DPr < 103 %, Ev2/Ev1 must be ≤ 2.5. Ev2/Ev1 ratios higher than 2.2 or 2.5 are permitted if the Ev1 value is at least 0.6 times the required Ev2 value.

base course aggregate compaction
Whenever compaction of pavement structure is presented, it is always a good idea to identify CLEARLY (a) the type of material (i.e., crushed stone aggregate, river gravel, etc) (b) the compaction method used (i.e., standard or modified Proctor (light or heavy tamping for our British friends). This establishes facts that anyone making a reply will want to know
Around trees compaction is not so good, but not putting a trail next to trees is nearly impossible in most of the country, and provides a nice user experience. One solution is to add soil over roots where trees are crossed by trails in their drip line. Another option is to not deduff in this area and/or add more mulch to protect roots, although mulch is typically not an ideal trail tread

Fundamentals of Soil Compaction
Figure 4 Effects of compactive effort on compaction curves It can be seen from this figure that the compaction curve is not a unique soil characteristic. It depends on the compaction energy. For this reason it is important when giving values of (γdry)max and mopt to also specify the compaction procedure (for example, standard or modified).

Compaction Methods* Dumped - Soil is dumped into place with no compactive effort. Sluicing - Soil is washed into place with a high velocity stream of water.

So for waste that is not homogeneous (which is what you would commonly find in self-haul, roll-off, and contractor loads), the teeth become infinitely more vital to the compaction process. This is especially true when the wastestream includes a higher percentage of C&D material.
