The down sides are the stones themselves. In CA where I lived they would do this. Once the stones went down a multi-tire roller machine went over the surface at least once to start the setting process. Then drivers drove on it for at least a week before any loose stones were swept back up.

I hit a fairly fresh section of road on my bike once and had to stop a couple of times to get the stones and tar out of my brakes so my wheel would turn. Plus it is quite dangerous for cyclists because loose stones tend to be swept by cars to the sides of the roads where cyclists tend to ride.
