crushed stone proctor density Nov
Engineering Experiinent Station - Iowa
Engineering properties of the two crushed stones are shown.in Table 1. The Bedford stone contains more gravel, less sand and more clay size particles, and has a measurable plasticity. The optimum moisture content for compaction is higher and the compacted density lower than for the Garner sample.

Compaction specs for crushed Stone Under Foundations ...
We normally recommend a No. 57 gradation crushed stone or gravel, and a thickness of 8 to 10 inches. If thicker layers are used, we recommend that each 12-inch thickness of stone backfill be densified by making 3 or 4 passes of a walk-behind vibratory sled or plate type compactor over the stone surface. Density testing is not performed.

How much volume is lost after compacting 3/4" crushed stone?
The loose drop weight of a relatively uniform (all the rocks are similar size and shape) 3/4" stone will be about 80-90% depending on the stone (angularity and phi). Presuming that you are compacting to of some form of "proctor density", because you're awesome at compacting and have a monster machine (and thin lifts), that's 100/80=125%.

Structural Soil — Part 1 – The Field
The maximum estimated dry density from the moisture-density curve is defined as Proctor density (see graph below). The actual dry density at Proctor will vary depending on soil texture or stone aggregate size distribution. In the field, it is often required that soils or bases under pavement be compacted to within 95% Proctor density.

Proctor compaction test - Wikipedia
The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density.The test is named in honor of Ralph Roscoe Proctor [], who in 1933 showed that the dry density of a soil for a given compactive effort depends on the amount of water the soil contains during soil ...

Proctor testing of 3/4" clean stone - Soil testing ...
I have not seen a procter for crushed stone. Typically the stone is placed in 12-18" lifts and tamped once or twice. The stone is so much stronger than the soil and is unaffected by moisture content that lab or insitu density testing is not done. We use it in freezing weather to backfill when soil would be impossible.
