The National Stone, Sand and Gravel Association is the leading voice and advocate for the aggregates industry. We advance public policies that protect and expand the safe, environmentally responsible use of aggregates that build America's infrastructure and economy.

Gradations. The dividing line between fine and coarse aggregate is the 3/8inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate. The FM is calculated by adding the cumulative percentages by mass retained on each of a specified series .

AGGREGATE SIZE (following description of system and example are colour coded to aid understanding) Sizes are described in terms of a lower limiting sieve size, "small" d, and an upper limiting sieve size, "big" D. Written as d/D [note the slash is just a separator, it is not little d divided by big D].

The density of stone ballast of a standard size is approximately 100 pounds per cubic foot that is Metric Tons per cubic.

A. Install stone columns with a downhole vibrator capable of densifying the aggregate by forcing it radially into the surrounding soil. The vibrator shall be of sufficient size and capacity to construct stone columns to the diameters and lengths shown on the installer's approved construction drawings. B.
