I called the local power company to ask them to fix an access road
washout at a swale and they did fix the drainage ditches, saying it took
them a long time and that they had to use "8 inch minus rock".

What's 8 inch minus rock anyway?

Give it some more thought and consider if you were screening material
for the maximum size that would pass with no regard for the minimum.

I think the minus refers to smaller content anywhere down to fine particles.

Rock 8" or less, down to a given size. For example I bought rock at
3/8" minus which some rock was smaller than 3/8" for landscape.

Generally, there is a point of just how small the "minus" is. Ask
them how small the minus is.

Depends on how they crush the rock. You may get 8 inch down to 3
inch. Not all the rock is the same size.

1.5" plus or 1.5" minus (with dirt)

And the opposite kind of rock, "eight inch no minus", means that they
seperate out the fines leaving you with only rock sized to eight inch
size.

Since this requires additional steps, it is generally a little more
expensive.

Nothing. Unless the OP wants to pay for the dirt.

Nothing. It's 8" and smaller. Sand will fit through an 8" hole.

Strange. I said almost exactly the same thing an hour before you.

Echo's in here?

Things must be called differently in various regions, here it would be
called "eight inch crusher run", meaning everything that leaves the crusher
that is 8" or less.

Must be a very local term. I'll bet spec sheets show it as "8"
minus". That is the technical term.

I've heard it called "x inch fines" in some areas, and I'd bet there are
other descriptors as well.

Being "called" something and a technical term appearing in a spec
sheet can be, and often is, entirely different.

Here "fines" refer to rock chips so fine as to be almost dust mixed
included in 3/4 or 1/2" minus used for top dressign gravel drives -
makes a really solid surface almost a blacktop finish. For all I know
"fines" is a tech term.
