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
Division 9 Materials 900 Definitions and Tests "Fractured aggregate is defined as an angular, rough, or broken surface of an aggregate particle created by crushing, or by other means. A face is considered a "fractured face" whenever onehalf or more of the projected area, when viewed normal to that face, is
Dec 01, 2014· Sieve Analysis (ASTM C 136, AASHTO T27): This test method evaluates the gradation of aggregate using a series of sieves. The results are then plotted on to a semilog aggregate gradation chart. This chart shows the particle size distribution for any given aggregate and can then be better evaluated for its use in portland cement concrete and ...

Aggregates used for stone matrix asphalt mixtures are required to meet the requirements of AS aggregates in accordance with Section (a). These requirements include testing with the MicroDeval abrasion apparatus (AASHTO T 327) and determination of the aggregate degradation in accordance with ITM 220. Additional requirements for . . . in .
the aggregate. The gradations should be current and are typically the average of more than one individual test for each aggregate. The following chart shows example individual aggregate gradations and combined aggregate gradation information. This chart contains all the data needed to produce the three aggregate optimization charts.
AASHTO #57 Stone Specs AASHTO #57 stone as defined by quarries, state agencies, etc. is an opengraded, selfcompacting 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 FlexiPave surfaces.

The AASHTO Soil Classification System was developed by the American Association of State Highway and Transportation Officials, and is used as a guide for the classification of soils and soilaggregate mixtures for highway construction purposes. The classification system was first developed by Hogentogler and Terzaghi in 1929, but has been revised several times since.
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.
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.
