In SW Indiana, there's miles of glass smooth new pavement on some great cycling roads -- very low traffic. I'm not sure where these rural low population counties got the funding.
They also chipsealed a couple of main roads, but it's that pea sized rounded gravel, with a top coat of tar. Not too annoying even when new, and smoother after a year of car and truck traffic.
Farther north in Indiana, they liked the rough larger gravel, very buzzy to ride on. I avoid those areas now. I'm sure it lasts more years, if that's important to them.
