Abstract
A plate for laying as a road surface in the vicinity of a railway comprising resilient rubber material delimited by three or more edges, at least one of which is provided with teeth to lock the plate with an adjacent plate against relative movement at right angles to the bearing surface of the plate, the plate being deformable to allow installation of a plate into position alongside already installed plates. The plate may have side edges adapted to fit closely to the rails, with or without a groove for rail wheel flanges. The shapes of the plates are chosen to fit the area between the permanent road, the rails and the side edges of the level crossing.
