The quarter minus rock size can consist of rock in diameter as big as 1/4" in size and "fines" (anything smaller than the maximum allowable rock size (which in this case is 1/4), even as small as stone dust). Any aggregate with the name "minus" can contain up to 80% fines.
The base material should either be 3/4" crushed stone (to allow water to drain through it) for a 1/4" crushed stone bedding, or 3/4" minus crushed stone (to prevent sand from sinking through it) for a concrete sand bedding. The base should be compacted every 6".
Substitutes for crushed stone used as construction aggregates include sand and gravel, iron and steel slag, sintered or expanded clay or shale, and perlite or vermiculite.

A sieve analysis (or gradation test) is a practice or procedure used in geology, civil engineering, [1] and chemical engineering [2] to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction ...

Crushed stone may be made from granite, limestone, dolomite, and other rocks. Also known as "crusher run", DGA (dense grade aggregate) QP (quarry process), and shoulder stone. [30] Crushed stone is distinguished from gravel by the U.S. Geological Survey. [25] Fine gravel gravel consisting of particles with a diameter of 2 to 6.3 millimetres (0. ...
The great majority of crushed stone is moved by heavy truck from the quarry/plant to the first point of sale or use. According to the USGS , 2006 U.S. sand and gravel production was 1.32 billion tonnes valued at $8.54 billion (compared to 1.27 billion tonnes valued at $7.46 billion in 2005), of which 264 million tonnes valued at $1.92 billion ...
Unbound granular materials are usually crushed stone, [3] crushed slag or concrete, or slate. Cement-bound materials come in multiple types. Mass concrete is used where exceptional loads are expected, with thickness usually 100 to 150 millimetres (4 to 6 in ), and optional reinforcement with steel mesh or polymer fibers.
