These are very common along the shore, especially out on Cape Cod. My
brother is a realtor and occasional house builder out there. They are
generally easy to deal with, but will have two problems for you.
First, they are very expensive. You'd think they'd be almost free, but
no. On the Cape, they are easily 50% over asphalt, and they may need
to be refreshed every couple of years. Second, give up any thoughts of
snowblowing. It's like gravel in that regards. Bad for the blower and
really bad for anything downwind of the blower outlet.

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.

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.
