This is a Wirtgen 2200CR Cold-In-Place asphalt recycler. It's a single unit train that grinds up 3-5" of the old road, and lays it back down as new road.
Production rates push 500 meters to 2km per HOUR.
Below that is what the full train looks like. The recycler is hooked to a bitumen truck and a water truck in front. And if a cement/lime additive is needed, they drop spread it in front of the grinding house.
All in all you get ~4 workers on the recycler, 2 trucks, and some rollers behind, and you've got a new road. Insanely efficient. No material hauling. The only thing you haul is the oil and water, and the thin seal coat on top (slurry, thin hot mix, chip seal, etc). I don't think MB does cold-in-place recycling. At least not this efficient. USA, Ontario, and Alberta do it. But correct me.
Fast is cheap. Fast is fast. Recycling is greener.
