Sieve Analysis. In order to determine the relative proportion of different particle sizes available in an aggregate mix, sieve analysis or gradation test is to be performed. In this test, the sieves are arranged in descending order of their opening sizes and are stacked over each other as shown in Fig. 5. Fig. 5: Stack of Sieves.
In late 2011, the proficiency test for determining fine aggregate gradation and sand equivalent was . These proficiency tests were based on two California Test (CT) methods. Namely, CT 202 "Method of Test for Determining Sieve Analysis for Fine and Coarse Aggregates" and CT 217 "Method of Test for Sand Equivalent".
Sieve analysis. Sand is characterized by a sieve analysis. A sieve analysis is performed using a set of stackable mesh trays (sieves) with hole diameters starting large and getting progressively smaller (9.5 to 0.075 millimeters). The sieves have numbers that correspond to the number of holes per inch in the mesh for sieves #4 and finer.
The frequency table has a provision for reducing R-value testing, but exercise caution when doing so. Consider reducing frequency when the initial test results show R-values significantly exceeding the specified R-value and ongoing gradation and sand equivalent test results indicate acceptable and consistent material quality.
four test specimens. c. Split or quarter the premeasured material to obtain a test specimen. Two successive splits will provide a specimen of the proper size. Do not make adjustments to the specimen size by adding or removing material at this time. 3. Dry the prepared test specimen to constant mass at 230 ± 9˚ ˚F and cool to room temperature.
A sieve analysis or gradation test determines the distribution of aggregate particles by size within a given sample. This information can then be used to determine compliance with design and production requirements. Data can also be used to better understand the relationship between aggregates or blends and to predict trends during production.
The fine aggregate angularity (FAA) test (Figure 1) is an indirect method of assessing the angularity of fine aggregate. Fine aggregate angularity is important because an excess of rounded fine aggregate (often in the form of natural sand) can lead to HMA rutting. Figure 1: Fine aggregate angularity test. The FAA test estimates fine aggregate ...

Assuming the permeability of the sand follows Hazen's empirical relationship, (k = D 10 2), the uncertainty associated with the D 10 values in Table 2.3 will propagate to the calculated permeability of the sand.The factor by which the permeability will change due to the uncertainty of D 10 can be expressed as D 10(Avg ± 1σ) 2 /D …
testing efforts. Improper and/or inconsistent sample collection procedures will introduce unwarranted errors in the test results. Poor sampling procedures can result in test results that make a good rootzone material appear to be inconsistent and therefore of poor quality. There are two levels of sampling and testing that should be carried out.
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 ...
The Aggregates (fine + coarse) generally occupy 60% to 75% of the concrete volume or 70% to 85% by mass and strongly influence the concrete's freshly mixed and hardened properties, mixture proportions, and economy. All Aggregates pass IS 4.75 mm sieve is classified as fine Aggregates.
Sieve analysis is a method that is used to determine the grain size distribution of soils that are greater than 0.075 mm in diameter. It is usually performed for sand and gravel but cannot be used as the sole method for determining the grain size distribution of finer soil. The sieves used in this method are made of woven wires with square ...
