Abstract
A method of constructing a rail track on a track-receiving concrete slab provided with channels serving to receive the rails of the rail track, wherein, after the concrete forming the track-receiving slab has set, it comprises at least the following steps: a) the stretches of rail are put in place above the channels in the track-receiving slab, each rail having a foot coated with a casing of resilient material; and b) the foot as coated with its casing is inserted into the channel by force.

A method of constructing a rail track on a track-receiving concrete slab provided with channels serving to receive rails of the rail track, wherein, after the concrete forming the track-receiving slab has set, said method comprising:
- a) putting stretches of the rails in place above the channels in the track-receiving slab, each rail having a foot coated with a casing of resilient material whose thickness is such that the foot as coated with its casing is slightly wider than the channel;
- b) inserting the foot as coated with its casing into the channel by force, the shape of the channel being suitable for reacting to the compression forces from the resilient material of the casing with a reactive force tending to hold the rail at the bottom of the channel;
- and
- c) filling the empty volume situated in the top portion of the channel on either side of the rails with resin which seals the installation.
