Roadwork Filter: The road adjoining mine is being resurfaced. About 2 weeks ago, the surface got chewed up and roughened by one of those enormous road scrapers.

Then they put down new asphalt and atop that, a thin layer of what looks like a fine bluestone gravel.
After about a week, they swept up that gravel; then yesterday, they laid down a new, thicker layer of the same type of gravel. They've also posted signs to the following effect: "Warning. Loose stones on road. Speed limit 15mph"
What's the purpose of this layering of gravel on the new asphalt?
