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.
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

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 ...
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.
SIEVE ANALYSIS OF FINE AND COARSE AGGREGATES AASHTO T 27 SCOPE The sieve analysis, commonly known as the gradation test, is a basic essential test for all aggregate technicians. The sieve analysis determines the gradation (the distribution of aggregate

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

C. Aggregates for Optimized Gradation. 1. Coarse Aggregate Requirements. a. Coarse aggregate includes all aggregate particles greater than or retained on the ½inch sieve. b. The physical requirements for coarse aggregate are as specified in Table 9022 for Class 6AAA and the following: i. Maximum 24 hour soak absorption of percent; ii.
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.
