left is filled with large aggregate particles of uniform size (AASHTO M 6/ M 80) plus an additional six more coarse aggregate size numbers. Fine aggregate or sand has only one range of particle sizes for general construction and highway work. The grading and grading limits are usually expressed as the percentage of material passing each sieve ...
Where standard sizes of coarse aggregate designated by two or three digit numbers are specified, the specified gradation may be obtained by combining the appropriate single digit standard size aggregates by a suitable proportioning device which has a separate compartment for each coarse aggregate .
dried the samples are cooled to room temperature, then reduced to testing size in accordance with AASHTO T 248. After reducing the aggregate to the proper testing size the first test performed in this example will be a washed gradation. Washing the sample will be done in accordance with AASHTO T
Some contract documents specify certain aggregate sizes for specific uses or may suggest one or more of these sizes as appropriate for the preparation of various endproduct mixtures. In some cases, closer limits on variability of the aggregate grading are required.

AASHTO No. 57: AASHTO 57 crushed stone is a clean material that won''t compact and features a 1 1/2inch top size. Typical applications include as backfill for retaining walls, as well as a subbase for sheds and driveway gravel or stone. Many readymix concrete and hotmix asphalt products contain No. 57 aggregate as its primary ingredient.

AASHTO #1''s are too bulky to be used as a surfacing material, however, it makes an excellent stone for subgrade stabilization. Applications for this stone include construction entrances and ditch lining. It will not compact, and is a clean material.
AASHTO T32712 or ASTM D692817: Perform the test using a 1500 ± 5 g sample (AASHTO Table 2, ASTM Section ), where the nominal maximum size of the coarse aggregate gradation is mm or less. Run the abrasion procedure in accordance with the interval or rotation as specified for a mm nominal maximum size aggregate.
