The standard gradation and sieve analysis test is AASHTO T 27 and ASTM C 136 Sieve Analysis of Fine and Coarse Aggregates Background. The particle size distribution, or gradation, of the constituent aggregate Figure 3 is one of the most influential characteristics in determining how an HMA mixture will perform as a pavement material.

7.9.10 Rock Gradation The gradation of stones in riprap revetment affects the ripraps resistance to erosion. The stone should be reasonably well graded throughout the riprap layer thickness. Table 7-9 presents the median particle size of three types of riprap which have gradations defined in the ConnDOT standard specifications.
Granular Material Type B. For Item 204, furnish the gradation of Items 304, 411, or 617. For Item 203, furnish the gradation of Items 304, 411, or 617 except 0 to 20 percent will be allowed to pass the No. 200 75 m sieve. 3. Granular Material Type C. Furnish well graded material that meets the following gradation

The coarse aggregates shall otherwise conform to the requirements of AASHTO M 80, with the following exceptions and stipulations
1. The listed AASHTO designations are for gradations only. The stone must also be clean, crushed, angular. For example, a specification for 4 stone would state Clean, crushed, angular No. 4 AASHTO
AASHTO serves as a liaison between state departments of transportation and the Federal government. AASHTO is an international leader in setting technical standards for all phases of highway system development. Standards are issued for design, construction of highways and bridges, materials, and many other technical areas.

TRUEGRID recommends to use AASHTO 571 stone or a similar -1.5 uniformly graded clean angular stone for the base material. The fill material can also be 57 stone or a similar - clean angular stone. All of these materials provide a 40 void space which is a common industry standard.
AASHTO table. Gradation - Gradation is the particle size distribution of aggregates determined by using sieves with square openings. The percentage of materials allowed to pass each sieve is usually referred to in the specification for the intended item. For instance, the specifications may call for an AASHTO No. 57. The gradation,
Gradation Numbers 24, 25, 3, 4A, and 4 are main line ballast materials Gradation Numbers 5 and 57 are yard ballast materials. 2. Old Pa The old Pennsylvania Department of Transportation reference to aggregate sizing. 3.

I do not believe it is referred to as AASHTO 57 stone, however, 57 stone as defined by quarries, state agencies, etc. is an aggregate blend of size 5, 6, amp 7 stone. This material cannot be compacted in a true sense, but can be properly oriented with compaction equipment.

Charge the contractor for the cost of sampling and testing potential local materials sources in accordance with Section 6, Control of Materials, of the Standard Specifications. The typical time required for testing initial source samples of potential local materials sources is
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 38 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.
