Abstract (en)
[origin: WO2008128665A1] The invention relates to a method and device for partially or completely foaming the hollow spaces in the ballast structure of a ballast bed, below which a subgrade (7) is located, having a reactive plastic, wherein the reactive components are mixed in a high-pressure mixer (1,26) and wherein the start time for the reactive mixture (4) is adjusted such that the foaming process substantially only begins when the reactive mixture has reached the subgrade (7).
