SPOORWEGCONSTRUCTIE, WERKWIJZE EN FILTERBEDSAMENSTELLING.

摘要

A railway construction comprises a substructure (10) on which a superstructure (20) is arranged. The superstructure comprises a ballast bed (24) with a series of sleepers (23) which are placed at least substantially regular mutual distances and to which a pair of at least substantially parallel rails (21, 22) is connected. A water-permeable stabilizing layer (25) is provided between the superstructure and the substructure. According to the invention the stabilizing layer comprises an at least substantially continuous, at least substantially homogeneous granular filter bed of a composition in which a microfine mineral powder is applied. According to the method the composition is suspended with water in order to form a liquid slurry and spread onto the substructure. A water fraction in the slurry is allowed to escape therefrom.
