In South Carolina we use crushed oyster shell.
Shell has to be washed to remove salt an other contaminants.
There are commercial crushers who resell.
Crushed shell is sprinkled over surface of concrete before it sets up.
It is then trowled in, concrete is allowed to set up overnight then
the top surface is hosed down to expose shell
It's best to find a pro with experience in the process.

That must be hell on your knees! Crouching down to work on the car is bad
enough with the concrete digging into your knees, now you guys throw in
oyster shell to tear your clothing as well?
If I could make my driveway out of rubber I'd do it.
Actually, what I'm talking about is a bed of crushed stone tamped
down, then the top layer is crushed shells. Sort of like a pea stone
driveway, but using shells instead of stone.
I work on cars in the garage, not the driveway;+}

If you really want to investigate, start calling aggregate places
along the shore, from north shore MA to southern ME. They are more
common farther south, but transportation costs will kill you.
The weather is so much nicer in the driveway than in the garage.

I drove around south of New Orleans 40 years ago, and the roads were
broken or crushed shells with no concrete at all. I didn't get out
and dig, but I think they were shell pieces all the way down to the
dirt. I'm sure that's still true for most of them.

I started taking down those plastic advertising signs on on poles or
wire legs, and later I found many uses for them. One is, I put a
large one under my knees before I work under the dashboard. Works
great. Many other uses.
