All I can say is that in the Cleveland area with rework that has occurred on some roads the tech has improved enough that it doesn’t take as long or as much man-power to redo an entire road.
I go on a 4 lane stretch for part of my daily ride.
- First day, they shut off 1 lane on each side of the median for about a 5 mile strech.
- By the next morning that lane was ground down at least 6 inches to the base.
- By end of the 3rd day new material had been layed on that stretch both sides of the median.
- End of the 4th day the lane edge stripe was painted and it was open for business, cones were already setup for the 2nd lane on each side.
- Repeated and within a 10 day stretch that 4 lane 5 mile stretch was completely new.
Only exception was the small concrete bridge - which went through some level of inspection based on the people I saw down underneath it.
They picked up and moved 5 miles down the road to repeat the whole process on the next stretch.
Minimal traffic impact during the whole thing. I guess my point is it doesn’t take as much time or manpower to do a stretch of road as it used to.
I doubt the total cost have come down.
