I've seen plenty of rotomilling but when they redid the road where I live they used a technique I hadn't seen. It was chip seal that hadn't had much maintenance for thirty years I know of. They ground up the pavement in place and redeposited it with some fairly large chunks. Riding a bike on it was a real pleasure. Then they went away for a month or so, let traffic compact it, and came back to lay down real hot top. We'll see how that goes. Most of the city streets are periodically chip sealed and they develop deep enough ruts that you have to be careful when you stop for a light on a bike.
