HOW TO CLASSIFY AGGREGATES ACCORDING TO SIZE?

 · According to size coarse aggregate is described as graded aggregate of its nominal size i.e. 40 mm, 20 mm, 16 mm and 12.5 mm etc. for example a graded aggregate of nominal size 20 mm means an aggregate most of which passes 20 mm IS sieve.

Graded Gravel

Well-graded materials have grain size characteristics approximating Fuller''s curve, i.e. there is a stable structure and only a small fines content is required to achieve low permeability. This type of liner exhibits less shrinkage on losing water, but they are not as flexible as earthen materials with a high clay content and this can be a disadvantage in the event of differential settlement.

Density of Aggregate

Density is an important parameter for aggregate. For aggregates, density is determined by multiplying the relative density (specific gravity) of the aggregate times the density of water. Bulk Density of Aggregate [1]The bulk density or unit weight of an aggregate is the mass or weight of the aggregate that required to fill a container of a specified unit volume.

Aggregate | Washington Asphalt Pavement Association

The typical graph uses the percentage of aggregate by weight passing a certain sieve size on the y-axis and the sieve size raised to the n th power (n = 0.45 is typically used) as the x-axis units. The maximum density appears as a straight line from zero to the maximum aggregate size (the exact location of this line is somewhat debatable, but the location shown in Figure 2 is generally accepted).
