— Crushed stone varies in size. The number "57" is a number that refers to the size sieve that was used to screen and sort the stone. It means that the stone was put through the #57 sieve which produces gravel stones of about 1" to 1.5" in size. #1 crushed stone refers to the largest sized crushed stone. It is about 2″ to 4″ in size.
CR6 crushed stone has many names, such as 21-A, road stone, dense grade aggregate (DGA) and quarry process (QP). CR6 contains crushed rock and stone dust because it has been carefully blended and graded to create a low-void content mixture. ... CR6 is a compactable aggregate that can fill voids between larger aggregates for projects like …
— You could specify the voids and let the contractor select the stone. Or you could specify 1.5" to 3" clean stone, as others have suggestes, but the actual voids will …
Interlocking concrete permeable paving allows storm water to enter the paving through the crushed-stone-filled joints, then pass through to a layer of larger crushed stone, before entering a lower level of crushed stone voids for storage. Within these voids, naturally occurring micro-organisms digest oil and other pollutants that have accumulated.
Type 1 stone is the largest of the crushed varieties and is great for filling large voids. You can also use this aggregate for road bases and construction entrances. Class 3 stone: Class 3 stones are slightly smaller than class 1 and an excellent choice for drainage and railroad projects.
Gravel typically has a void ratio about 0.4, regardless of whether it is well or poorly graded, although the void ratio can be affected by the presence of impurities, such as clay or silt. Gravel with clay has a void ratio of about …

In soil mechanics, the void ratio describes the relationship between the volume of voids, or spaces, in the soil or aggregate to the volume of solid constituents, or grains. Algebraically, e = Vv /Vs, where e represents the …
The volume of the voids did not vary in direct proportion with the depth within the aggregate, as is assumed in current design methods. In general, the more rounded aggregates, such as the gravels, had a smaller volume of voids than the more angular crushed stone. In some instances, the difference
The next layer is a stone reservoir consisting of uniformly graded, clean crushed stone with 40% voids serving as a structural layer and temporarily storing water as it infiltrates into the soil below. To stabilize the surface for paving, a thin (about 1 inch thick) layer of clean, smaller, single-size crushed stones is often

— The frost depth is 4'. My pile caps are 2.5' thick. Can I fill the bottom to frost depth with something flowable, like 3/4" crushed stone? I saw discussions here about using void forms, but this is a pile cap and it'll be pretty difficult to place styro around a pile.
the voids of crushed stone compaction piles over time. In this study, research was performed to reduce clogging and minimize voids in a crushed stone compaction pile constructed in soft ground. An optimal mixing ratio was …
Soil void ratio (e) is the ratio of the volume of voids to the volume of solids: e = (V_v) / (V_s) Where V_v is the volume of the voids (empty or filled with fluid), and V_s is the volume of solids. Void ratio is usually used in parallel with soil porosity (n), which is defined as the ratio of the volume of voids to the total volume of the soil ...
Crushed stone is a type of aggregate formed by breaking down larger rock formations to specific sizes. The stones are then categorized into different grades based on the sizes of the pieces produced after crushing. ... The …
Lesser dimension of aggregate have higher density due to less presence of air voids & higher dimension of aggregate have lower density due to higher presence of air voids. ... Unit weight or density of 10mm, 12mm, 12.5mm, 20mm & 40mm coarse aggregate/ crushed stone/ gravel/ coarse sand is ranging between 1425 kg/m3 to 1575 kg/m3, it means ...
Sand or fine crushed stone used for filling voids in course aggregate.Generally less than ¼" and greater than No. 200 sieve. Amplitude The vertical distance the vibrating drum or plate is displaced from the rest position by an eccentric movement.
Put down a base layer: If needed, add a layer of smaller crushed stone or stone dust to fill any voids and create a smoother surface. Final Compaction and Leveling: Compact again: Once the base layer is down, compact …

AASHTO #57 Stone Specs AASHTO #57 stone as defined by quarries, state agencies, etc. is an open-graded, self-compacting aggregate blend of size 5, 6, & 7 stone. This material cannot be 'compacted' in a true sense, but can be properly oriented with compaction equipment. This is particularly important when using #57 stone under Flexi-Pave surfaces.

#1A Crushed Stone is a versatile aggregate material with various applications. The stone is considered self-compacting, allowing it to efficiently settle into a dense and stable arrangement under its own weight. Easily fill voids and spaces, ensuring efficient and uniform compaction without the need for additional compaction efforts.
vibrating roller. On the three graded crushed stone materials, somewhat higher densi ties were obtained with the vibrating roller, while on the fourth, a local pit material containing only about 2 percent plus No. 4 aggregate, the highest densities were ob tained with the heavy pneumatic-tired roller. In 1961 the field experiments were con
The proper material is a crushed angular gravel mix with NO fines. The base typically consists of two to three different layers. The first base layer and consists of 3/4 inch crushed angular rock that will have void spaces between 25-40%. The sub base layer used in heavier loading situations typically consists of 1-2 inch size crushed angular rock.
— Stone storage is commonly designed with a best-case value of 40% voids, hence my concern that the terms may have been swapped. As long as everyone is using the same parameter... Your void ratio or 0.40 is equivalent to .4/1.4 voids = 29% voids, which is probably more realistic than the common 40% value. Peter Smart HydroCAD …

— But a mix of sand and big rock will end up with sand filling 70% of the voids in the big rock. so you get 30% of 30% void = 9%. ... Washed round (river) rock leaves large air gaps between each stone, as opposed to crushed rock which fits more tightly together when settled.
