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.
Products in this range are notably more compactible and suited for creating a base layer -such as Crusher Run, Screenings, Sand and Soil. For support of heavy vehicles – choose our #3 or #4 stone. For standard driveways – choose our #57 or #67. For more elaborate driveways – choose our 1/2” to 2” river gravel.
610 is a commonly specified dense-graded crushed aggregate in the Southeast. From a gradation standpoint it usually runs from 3/4 inch to dust, and maximum dry density for a limestone or dolomite derived aggregate is on the order of 140 pcf.
Crushed stone #1 is the largest of the crushed stone grades and includes stone that is between 2-4 inches. This materials is great for larger jobs or for filling in larger holes. #3. Crushed stone #3 includes stone between 1/2 and 2 inches. This material is a great choice for railroad projects and those that require drainage.
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.

Dense-graded base course refers to crushed stone aggregates with a range of particle sizes, usually 1-1/2-inch and smaller, that produce a dense layer of stone with a minimum amount of voids. Common uses for base coarse crushed stone • Foundation for asphalt pavement • Foundation for concrete pads and pavements • Unpaved roads and shoulders
Accessible crushed stone trails should be designed and constructed at grades less than 8% grade to promote accessible use. Overall trail grade averages of less than 6% will provide the most user-friendly experience and offer the most sustainable natural trail surface if compacted crusher fines are to be used.
Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers.It is distinct from naturally occurring gravel, which is produced by natural processes of weathering and erosion and typically has a more rounded shape.

Returning to the definition of quality aggregate, it is amazing how much research money has been spent trying to find a clear usable definition of quality aggregate. One $55, QOO project in particular, performed at the graded crushed stone aggregate, must not be overlooked.
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.
1. Introduction. Graded crushed stone (GCS) is an unbound granular material for road construction, which is easy to obtain and of low cost, and is commonly used in asphalt pavement , .GCS base plays a significant role in spreading the wheel load response, providing support for the asphalt surface course, and protecting the subgrade underneath the base and subbase .
Use graded aggregate base, subbase, or shoulder course material of uniform quality. a. Obtain the graded aggregate from an approved source or deposit that will yield a satisfactory mixture meeting all requirements of this Specification. b. Use material that is crushed or processed as a part of the mining operations, or, mix two grades of
Finely graded for use in pathways and walkways as well as tennis courts, bicycle trails, horse rings, stables and barns. Can also be used for ice and snow traction grit, backfill for underground cable and storage tank bedding. Popular in concrete production, asphalt mixes, drainage and filter media, horse rings, and blotting stone.
Coarse aggregate can be described as uncrushed, crushed, or partially crushed gravel or stone. This type of aggregate is described as how it is graded. For example, ¾” nominal size graded aggregate means that most of the aggregate passes a 3/4” sieve.
Gradation of Aggregates Definition. The particle size distribution of an aggregate as determined by sieve analysis is termed as gradation of aggregates. If all the particles of an aggregate are of uniform size, the compacted mass will contain more voids whereas aggregate comprising particles of various sizes will give a mass with lesser voids.The particle size distribution of a mass of
FACES be crushed so that at least 50% gravels shall be by mass of the fractions retained crushed so that at on each standard sieve 4,75mm least 50% but. Mass and any larger shall have at least of the fractions one fractured face. retained on each standard sieve 4,75m and any larger shall have at least one fractured face.
is well graded has a uniform distribution of sizes, within a given minimum and maximum range. Void spaces between the larger rock are filled with the smaller material. Void space is reduced which results in a denser placement of riprap or aggregate that is less likely tosettle or move when under loads. Rock that is poorly graded or gap graded
