Abstract

A method for manufacturing an embedded rail track with a continuous and elastically supported rail embedded in a continuous concrete track bed, wherein a rail has a head, a web and a foot, which method comprises the steps of: - providing one or more pre-aligned rails provided with filler blocks on opposed sides of the web as well as with an elastic strip underneath the foot, - pouring the concrete track bed and allowing said concrete to harden thereby embedding said one or more pre-aligned rails in the concrete track bed. At the boundary between each filler block and the hardened concrete track bed a layer of the filler block is removed by machining to create a void to the level of the elastic strip. These voids created by said machining are filled by pouring into the voids a pourable resilient compound which cures over time and has permanent elasticity.
