1.3 Use Part II to determine a weightbased, sieve analysis for an aggregate sample requiring a washed sieve analysis. 1.4 Use Part III to determine a volumebased, sieve analysis for an aggregate sample. Perform a volumetric sieve analysis when aggregates with differences in bulk specific gravity greater than 0.3 are blended.
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 particles, by size, within a given sample) in order to determine compliance with design,

on the worksheet. The weight of minus 75 μm (No. 200) sieve material "Wash" is found by subtracting the "Wash Weight" from the "Dry Weight" of the test sample prior to washing. The sum of these weights must be within 3 g of the dry weight for combined (coarse and fine) and fine aggregate samples and within 10 g for coarse aggregate samples.
Nov 09, 2014 · The most important test is the sieve analysis of aggregate, whether it is 20mm, 10mm, 5mm and 1mm sizes. The crucial thing is I have to do it every delivery of aggregate and as per the frequency of sieve analysis, which is written in this article frequency of tests.

aggregate size numbers. Fine aggregate or sand has only one range of particle sizes for general construction and highway work. The grading and grading limits are usually expressed as the percentage of material passing each sieve. Fig. 56 shows these limits for fine aggregate and for one size of coarse aggregate.
METHOD OF TEST FOR WASHING AND SIEVE ANALYSIS OF COARSE AND . FINE AGGREGATE . SCOPE . This test method covers the procedure used to accurately determine the particle size distribution of coarse and fine aggregate samples including Base Aggregates, Aggregates for Bituminous Courses, Concrete Aggregates, and other selected materials.
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.
Dec 01, 2014 · Aggregate is classified into two general sizes: coarse grained and fine grained. Coarse aggregate is rock retained on a 3/8inch (#4 U.S. sieve). Fine aggregates pass the 3/8inch sieve and are retained on a #200 U.S. sieve. 6. Fine Aggregate. Fine aggregate consists of natural sand, manufactured sand, or a combination.

to require a washed gradation in addition to or in place of dry sieving. These methods are not to be used alone for sieve analysis of aggregates recovered from asphaltic mixtures or for the sieve analysis of mineral fillers. The sieve analysis of mineral filler is to be determined in accordance with DOTD TR 102.
SIEVE ANALYSIS Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) – 1963. In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over
Sieve analysis has, in general, been used for decades to monitor material quality based on particle size. For coarse material, sizes that range down to #100 mesh (150μm), a sieve analysis and particle size distribution is accurate and consistent. However, for material that is finer than 100 mesh, dry sieving can be significantly less accurate.
