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.

Furnish the gradation of 100 percent passing the 8 inch (200 mm) sieve, less than 60 percent passing the 3 inch (76 mm) sieve, less than 40 percent passing the 3/4 inch (19 mm) sieve, and 0 to 20 percent passing the No. 200 (75 µm) sieve for Type D granular material.

Tables 1 through 5 have gradation guidelines for D50s of 4 inches through 12 inches. The smaller (i.e., 1 and 2 inch) diameters shown should be considered as "weight of material" rather than "number of rock." The tables can be used to produce gradation sample piles showing the upper and lower limits of the desired gradation.

2. Stone Aggregate for Concrete. Test aggregate before and after concrete mix is established and whenever character or source of material is changed. Include a sieve analysis to determine conformity with limits of gradation. In accordance with ASTM C75, take samples of aggregates at source of supply or at the ready-mix concrete plant.

Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 4.75 mm IS sieve. This is then broken down into four types of grading Zones 1 through Zone 4 with Zone 4 being the most fine. Coarse aggregate can be described as uncrushed, crushed, or partially crushed gravel or stone.

Crushed Stone Tilcon Connecticut's crushed stone operations comprise five quarries producing the finest crushed stone and two sand & gravel pits strategically located throughout Connecticut. Each year we process millions of tons of aggregate at our operations. The Tilcon quarries contain the highest grade trap rock deposits. The density and shape of Tilcon crushed trap […]

Size #3, for instance, is usually 1.5 to 2 inches (about 3.8 to 5 cm) in diameter, and is often best for residential draining projects; #8, which is usually 3/8 to 1/2 an inch (1 to 1.2 cm) across, is frequently used in asphalt and concrete mixtures. Gravel labeled #411 is usually a mixture of #57 and stone dust, and is particularly useful for ...

First, the base of the driveway or parking lot should be filled with large stone s. Number 2 Limestone is commonly used and is 3 to 4 inches of clean crushed limestone. This size resembles a lemon or grapefruit. Also, it cannot be shoveled by hand, so a skid-steer loader or dozer will work well to put the rocks in the desired position. ...

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.

Sieve mesh sizes are based on dimensions of the mesh size opening, or on the number of openings per linear inch. The two major standards governing test sieves and appropriate sizes are ASTM E11 and ISO 565/3310-1, both of which specify parameters for aperture dimensions, mesh size, and statistical variations. Opening sizes and mesh diameters for test sieves are often duplicated between these ...
