Abstract

The protective layer for the bed element (4), in particular, of a railway track consists of a watertight foil (2) covering the contact area between the bed element and an earth foundation (1), and abutting plate elements (3) capable of supporting large compressive loads and absorbing little water during their long-term contact with moisture.
