Navigating the world of gravel size can be as intricate as selecting the perfect gemstone According to the National Stone Sand & Gravel Association NSSGA the aggregates industry produces about billion tons of crushed stone sand and gravel each year with sizes ranging from fine powder to larger stones the size of golf commonly used numerical
Nominal aggregate size dictates lift thickness a mix containing ½ inch NMS stone should be placed at a compacted depth of at least 1 ½ to 2 inches If a ½ inch top size mix is placed at 1 inch compacted depth the mat may pull and tear and the stones may be broken by the rollers such as the use of blending charts might be
York Building Products offers type 1 aggregate in the Central Pennsylvania region Typically the higher the class number the smaller the stone size Finding the right crushed stone size is essential for project completion because each has a different capability and purpose and some projects may call for multiple types
Gravel Size Gradation Chart which stone to choose 2012· This classification defines aggregate size number designations and standard size ranges for mechanical sieve analyses of coarse aggregate and screenings for use in the construction and maintenance of various types of highways and bridges Units The values stated in SI units
The aggregates are broadly classified into two types based on the size namely fine aggregate and coarse aggregate The coarse aggregate shall consist of gravel crushed gravel crushed stone air cooled blast furnace slag or crushed hydraulic cement concrete or a combination thereof conforming to the specification as given below 1 Grading
The choice of maximum aggregate size depends on specific conditions with 40mm size used for normal strength concrete and 20mm for high strength applications Applications of Coarse Aggregates Coarse aggregates are fundamental in the construction of structures requiring high compressive strength such as high rise buildings dams and

COARSE AGGREGATE SIZES PERCENT PASSING Sieve Sizes 3/4 in 19 mm 2 in 50 mm 75 µ m sieve as determined by AASHTO T 11 and T 27 3 Decant may be for stone and slag 4 When slag is used for separation layers as defined in the total amount passing the No 200 75 µm sieve shall be to 4 in 100 mm
The mesh designates the size of the sieve openings in inches or millimeters defining the amount of material passing through the sieve Sieve opening sizes are determined using imperial units for apertures 1/4in or larger and the indicated range of these openings varies from 5 inches 125 mm to 635 mesh 20 microns This establishes
In some cases closer limits on variability of the aggregate grading are required 5 Manufacture The standard sizes of aggregate described in this classification are manufactured by means of any suitable process used to separate raw material into the desired size ranges Production of standard sizes by blending two or more different
The table below includes fine and coarse aggregate sieve sizes For geotechnical engineering gradation testing of soils using test sieves is governed by ASTM D6913 for soil particles as fine as 75µm No 200 sieve size
Aggregate granular material used in construction Aggregate may be natural manufactured or recycled Aggregate size description of aggregate in terms of lower d and upper D sieve sizes see later text Coarse aggregate designation given to the larger aggregate sizes with D greater or equal to 4 mm and d greater than or equal to 2 mm
X = Stone largely consists of this size = Stone can consist of up to 15% of this size = Stone can consist of up to 10% of this size Each stone gradation can contain up to 10% upper and lower grades and some fine material sand In the upper range of our stone sizing
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

The choice of maximum aggregate size depends on specific conditions with 40mm size used for normal strength concrete and 20mm for high strength applications Applications of Coarse Aggregates Coarse aggregates are fundamental in the construction of structures requiring high compressive strength such as high rise buildings dams and
The largest of the crushed stone grades  For larger jobs such a culvert ballast Crushed stone #8 â Sizes from 3/8â ³ to 1/2â ³ For concrete and asphalt mix Crushed stone #3 Sizes from 1/2â ³ to 2â ³ For drainage and railroad projects Crushed stone #10 also called stone dust â Screenings or dust
The mix has a gap graded aggregate skeleton with coarse aggregate stone on stone contact SMA is used on very high volume urban highways or very high volume slow moving traffic to resist rutting Aggregates for HL 3 HL 4 and Superpave and surface course mixes do not have specific requirements for frictional properties except
Crushed stone grades are categorized by fragment sizes after the stone has been crushed AASHTO #10 aggregate is on the lower end of the scale as it is ground very finely to create dust At York we use limestone to produce AASHTO #10 and other grades of crushed stone as this material is abundant in Pennsylvania AASHTO #10 Stone Size
A larger size 40mm is more common in mass concrete • Larger aggregate diameters reduce the quantity of cement and water needed 20 mm aggregate Common aggregates • Crushed Stone and Manufactured Sand Stone is quarried crushed and ground to produce a variety of sizes of aggregate to fit both coarse and fine specifications
