ROAD BUMPER Russian patent published in 2023 - IPC E01F15/08 

FIELD: road construction.

EFFECT: reduction in impact energy, a simplified design and an increase in the manufacturability of installation and repair of a road bumper. The road bumper consists of a concrete block installed on the dividing strip of the highway, on the opposite sides of which, facing the traffic lanes, there are protective layers made of extended damper shaped elements. On each side surface of the concrete block along its length there are continuous grooves in which damper shaped elements are fixed in the form of elastic bundles with the formation of artificial elastic ribs. The grooves can be made in the form of a dovetail. The damper elements can be made as prefabricated ones, in which the elastic strands are enclosed in an elastic shell consisting of a set of spring split rings, and the diameter of each elastic strand is equal to the internal diameter of the spring split rings. The elastic shell, consisting of spring split rings, can be made discrete.

SUBSTANCE: used to ensure reliable separation of traffic flows by bumpers on roads and highways.
