Grading of Aggregates. Grading of Aggregates is one which is made up of stones of different sizes, ranging from large to small (inclusive of sand) so as to have minimum of air voids (and that will have maximum density) when mixed together.In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate.
Stone size and sieve size are related (the sieve size is basically the minimum size the stone can be), but a stone size is actually an allowable range of sizes. For example, for a #4 stone, will pass through a 50-mm or 2-inch sieve (2x2-inch or 50x50-mm square sieve openings) and at least 95% must be larger than the opening in a #4 sieve.

ii) the percentage by weight of the total sample passing through one sieve and retained on the next smaller sieve, to the nearest 0.1 percent. The results of the sieve analysis may be recorded graphically on a semi-log graph with particle size as abscissa (log scale) and the percentage smaller than the specified diameter as ordinate.
Any gas pipe sand bedding material retained on a #4 sieve, shall not contain angular material as described in ASTM D2488. Gas pipe sand bedding material which contains subangular, subrounded or rounded material, and conforms to Sections 4.2.1 and 4.2.2 is acceptable. VOLUME 17 –ENGINERING & CONSTRUCTION STANDARD SUB01X TRENCH BEDDING AND BACKFILL
Sieve Analysis Gravel is made up of three groups of aggregate: stone, sand,and fines. Depending on what the material is to be used for, the ideal blend of these three groups varies greatly. For example, good surface material for a gravel road would need more material passing a #200 sieve than a good base material. There is also a difference in ...
