The joints might be a bit large for polymeric sand, though it would be the easiest thing to do in the circumstance you describe. Most manufacturers (Alliance, Techni-Seal, etc) will tell you the maximum joint width on the packaging.

Not a big fan of pea gravel in these situations as it is not particularly stable based on its rounded shape.

If gravel, then I might suggest decomposed granite as it packs down nicely and allows for drainage as well.

Not sure what you are referencing with "traffic bond gravel".

Good luck with the project.

Pea Gravel or delaware river rock sized 1", on top of an inch of stone dust to help stay in place. The larger the stones, the less likely they will kick out. Dogs can do the most to take out these types of stones, but the stone dust will help the stones to set, and will help to deter, but not stop completely, weeds from getting through.

Landis, this might work I like the look! I posted this question first on Landscape Design and there are a couple pictures of my path over there.
