AASHTO T 27 or ASTM C 136: Sieve Analysis of Fine and Coarse Aggregates; AASHTO T 11 or ASTM C 117: Materials Finer than 75-µm (No. 200) Sieve in Mineral Aggregates by Washing; AASHTO T 30, Mechanical Analysis of Extracted Aggregate, is used when performing gradation analysis on aggregates extracted from an HMA mixture. Summary
Gradation and SizeIn PCC, gradation helps determine durability, porosity, workability, cement and water requirements, strength, and shrinkage Because of this, gradation is a primary concern in HMA and PCC mix design and thus most agencies specify allowable aggregate gradations for both Maximum Aggregate Size.Combined Gradation ExampleConcrete Aggregate Combined Gradation Example

The important characteristics of aggregates for concrete are listed in Table 5-2 and most are discussed in the following section: Grading. Grading is the particle-size distribution of an aggregate as determined by a sieve analysis (ASTM C 136 or AASHTO. 80. Design and Control of Concrete Mixtures EB001. Table 5-1. Rock and Mineral Constituents
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.
Aggregate gradation curves: (a) maximum density gradations for 37.5 and 4.75 mm sizes based on the Fuller relationship; (b) a uniform aggregate; (c) a gap-graded aggregate; (d) screenings.
A gradation that, when plotted on the 0.45 power gradation graph, falls mostly below the 0.45 power maximum density line. The term generally applies to dense graded aggregate. Figure 2: FHWA gradation graph showing representative gradations. Permeability. Figure 3 shows some typical aggregate gradations and their associated permeabilities. This
Gradation of Aggregates Definition. The particle size distribution of an aggregate as determined by sieve analysis is termed as gradation of aggregates. If all the particles of an aggregate are of uniform size, the compacted mass will contain more voids whereas aggregate comprising particles of various sizes will give a mass with lesser voids.The particle size distribution of a mass of
