I'm laying a brick path more or less per the instructions here:

http://www.cornerhardware.com/howto/ht023.html

Those instructions call for "engineered road base" to be put under the
sand. I went to a big masonry supply store today and bought six sacks
of 1/4 minus gravel. I now realize that I probably wanted 3/4 minus--
that seems, based on some Googling, to be more like what is used as
actual road base. So my question is, what are the consequences of
using the 1/4 minus gravel that I have (and can't return)?

put some dry concrete in each of the six sacks of gravel and wet it lightly
when placing the bricks in.

Hmmm, what will that do? I guess I'm unclear on the exact purpose of
the road base so I can't figure out whether finer base is going to be
better, worse, or indifferent. Also I don't think I can wet it as I'm
putting the bricks in because at that point it'll be under a couple
inches of sand.

It sets the aggregate under the brick.......
It is a common practice.....
Some put raw concrete in sand and do the same.
Underground companies use a mixture of sand and concrete to set the subgrade
back to original.
Packed rock is just as good. (road base)

Go to a aggregate yard and get a 1/4-1/2 yard of "3/4 minus" or road base
if thats what they callit.
Cost: less than $ 10.00
Save the 'bags' for some other project
