1. I looked at the gravel you are using. I would suspect you might see 1/2 to 3/4 inch of compaction, especially if you just laid it down. All you can do is start compaction, see what it looks like and add or rake off a bit to meet you needs. Pretty subjective answer, sorry.

Soil Compaction:Ground Improvement Method Before House ...

 · Soil compaction is the oldest and most common method of soil improvement. It is the densification and reduction in the void ratio of soil through the explusion of air. Compaction of soil is a common practice to improve the various properties of soil.

SOIL COMPACTION AND STABILITY

Compaction involves an expulsion of air without a significant change in the amount of water in the soil mass. Thus, the moisture content of the soil, which is defined as the ratio of the weight of water to the weight of dry soil particles, is normally the same for loose, uncompacted soil as for the same soil after compaction.

What is the best gravel for compaction?

 · For example, specifications often require compaction to be 95 percent of Standard Proctor. This means the on-site soil density must be equal to 95% of the maximum achievable compaction. Compaction is achieved by applying three basic …

Proctor compaction test

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 ...

Subgrades & Subbases for Concrete Slabs

 · To get the best compaction, the optimal moisture content will typically be in the range of 10% to 20%. So when you hear that according to the specification the soil needs to be at 95% of the maximum modified Proctor density, you will know that you need the moisture content to be about right in order to get to that level of compaction.

Aggregate Base Course | Acme Sand & Gravel

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

Subgrades and Subbases for Slabs| Concrete Construction ...

 · The subbase, according to ACI 302.1, "Guide to Concrete Floor and Slab Construction," is a layer on top of the subgrade of "compactible, easy to trim, granular fill that will remain stable and support construction traffic.". In some cases, a base layer is placed on top of the subbase. All of these layers together comprise the soil ...

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%.

DYNAMIC COMPACTION | GROUND IMPROVEMENT | ADVANTAGES ...

 · Dynamic compaction is a ground improvement technique in which a drop weight is used to densify the soils and fill materials. The drop weight is typically made of steel and is lifted by a crane and repeatedly dropped onto the ground surface. The vibrations that are resulted from the repeated drops, are transmitted below the surface which improve ...

In soil compaction test, if a test result exceeds ...

Soil compaction is the process of increasing the soil density by reducing the volume of air within the soil mass. Soil compaction depends mainly on the degree of compaction and the amount of water present for lubrication. Normally 2.5kg rammers and 4.5kg rammers are available for compaction in laboratories and the maximum dry densities produced […]

Calculating Cubic Yards vs. Tons

A cubic yard is a measurement by volume (Or most simply put, a measurement by size) 2. A ton is a measurement by weight. 3. A "/" sign means ''per,'' so 1.5 TONS/CY reads 1.5 TONS per Cubic yard which simply means there are 1.5 tons per (for) every cubic yard of material. Fortunately, a cubic yard of material has a conversion factor (unit ...

Sand Compaction Pile

The constrained column-to-soil modular ratio varies in the range of 10–50, although the lateral expansion of the column (bulging) reduces the parameter n s significantly, sometimes as low as 5, due to plastic strains (Castro and Sagaseta, 2009). Mitchell (1981) reported the range of the value of n s as 2–6 based on field studies, while Han and Ye (2002) pointed out the typical value of n s ...

The Complete Guide to Crushed Stone and Gravel

 · Crushed stone: If you hear the generic "crushed stone" term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.
