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.

A plate for laying as a road surface between the rails of a railway track crossing, the plate comprising resilient rubber material delimited by at least three side and end edges, the length and relative orientation of said side and end edges defining a section of said road surface; said edges including at least one side edge shaped for interlocking relation with a complementary shaped side edge of an adjacent plate, and end edges shaped for interlocking relation with a respective inwardly facing side of one of said rails; said plate being resiliently deformable for insertion into said section of road surface and being self-returning to a non-deformed condition in which said interlocking relation of said edges is obtained so that said plate is held in a desired position with respect to the rails, the interlocking of the at least one side edge with the side edge of an adjacent plate and the interlocking of the end edges with the rails being the only means to restrict vertical movement of said plate, outer side edges of plates forming outer edges of the road surface being contacted by blocking means for restricting movement of the road surface in the longitudinal direction of the rails.
