<p>The machine has a formation protective layer conditioning unit (60) with a mixing device for mixing the layer with liquid treatment fluid. An old formation protective layer conveying device (52) conveys the partially conditioned layer from another formation protective layer conditioning unit to the former conditioning unit. A delivery line (71) conveys the fluid from a fluid tank unit to the mixing device, and a formation protective layer introducing device (100) introduces a new formation protective layer. A ballast introduction device introduces a ballast layer on an interlayer.</p> |
