Gradation and Size - Pavement Interactive

In 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

Sieve analysis - Wikipedia

A gradation test is performed on a sample of aggregate in a laboratory. A typical sieve analysis involves a nested column of sieves with wire mesh cloth (screen). See the separate Mesh (scale) page for details of sieve sizing.. A representative weighed sample is poured into the top sieve which has the largest screen openings.

Gradation Test - Pavement Interactive

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.

AASHTO #57 Stone Specs - Capitol Flexi-Pave

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 in Concrete - The Concrete Network

If there is a deficiency in a locally available fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material (SCM) to address these shortcomings. Broad coarse-aggregate gradation ranges are listed in Table 2 of ASTM C 33.

Gradation: Recycled concrete material should be crushed and screened to produce aggregate that satisfies the AASHTO M6 (5) and M80 (6) gradation requirements for PCC. With appropriate adjustments, a plant can produce any desired gradation. Crushed fine aggregates (minus 4.75 mm (No.4 sieve)) are generally not used or are blended with natural sand.
