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

4.1 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 end-product mixtures. In some cases, closer limits on variability of the aggregate grading are required.
All aggregates are porous, but some are more porous than others. How porous an aggregate is determines how much liquid may be absorbed when soaked in water. AASHTO T 85 defines absorption as the increase in the weight of aggregate because of water in the pores of the material, but not including water adhering to the outside surface of the ...
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 ...
AASHTO #57. This material has a 1-1/2 inch top size and is a clean material. Often used for backfill for retaining walls, used for subase for sheds, also sometimes used as driveway stone. Also used as the primary raw aggregate in Ready Mixed Concrete and some Hot-Mixed Asphalt mixes. Will not compact.

Reduce the sample from one of the two pans as many times as necessary to reduce the sample to meet the minimum size specified for the intended test.
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 T 27 - Standard Method of Test for Sieve Analysis of Fine and Coarse Aggregates Published by AASHTO on January 1, 2014 This method covers the determination of the particle size distribution of fine and coarse aggregates by sieving.
AASHTO T327-12 or ASTM D6928-17: Perform the test using a 1500 ± 5 g sample (AASHTO Table 2, ASTM Section 8.3), where the nominal maximum size of the coarse aggregate gradation is 12.5 mm or less. Run the abrasion procedure in accordance with the interval or rotation as specified for a 12.5 mm nominal maximum size aggregate.

Classification of Aggregates Based on Size. Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates.
The samples must be run through the following series of AASHTO procedures to then be further examined by our group of Engineers, Geologists and Technicians. AASHTO T 11 - Wash Test AASHTO T 27 - Gradation Analysis AASHTO R 76 - Reducing Samples of Aggregate to Testing Size AASHTO T 87 - Dry Preparation of Soils
Find the most up-to-date version of AASHTO M 43 at Engineering360. scope: This specification defines aggregate size designations and ranges in mechanical analyses for standard sizes of coarse aggregate and screenings for use in the construction and maintenance of various types of highways and bridges.
The AASHTO system ranks specs according to size (1-10), with 1 being the largest (all material must pass a 4" sieve) and 10 being the smallest (all material passing a 3/8" sieve). Multi-digit specs represent a blend of one or more of the ten basic specs (i.e. AASHTO 57 is a blend of AASHTO 5 and AASHTO 7).
Jan 24, 2013· By the CT 382 definition, the maximum aggregate size is 3/4" and the nominal maximum aggregate size is 1/2". In the November 2011 version of CT 202, nominal maximum aggregate size is defined as "one sieve size larger than the first size to retain more than 10%." By this definition the nominal maximum aggregate size for the material example ...
