He says that the smooth surface was underneath, and the loose gravel was just some leftover that they didn't bother to sweep off; I maintain that the gravel WAS the surface, and it packed down to smoothness over the course of about 6 months from all the neighborhood cars going over it, and that this was in fact the intended design of the product. But I can't find proof that such a thing exists. "Unbound surface aggregate" was the closest descriptor I could come up with from Google, but all the results are huge PDFs that I can't make much sense of.

I've learned the term "
chip seal" to describe the scenario in your neighborhood and on the street in front of our house. Your understanding is precisely correct.
