I've seen this in Texas, notably on I-35 through Austin and on I-10 east out near the state line. In sequence, single-file, all the machines needed to do the job, from milling the surface at the front to laying down the new blacktop, rolling it, and IIRC painting it. Just creeping up the highway. Pilot vehicles at the front and back to close/open the lane. Texas definitely throws money at the problem. Although lately they're optimizing their spend for larger checks to fewer contractors on bigger roads. Simplifies all the kickbacks I'm sure.
