MOBILE PAVEMENT Russian patent published in 2004 - IPC

FIELD: road building.

SUBSTANCE: invention relates to means of equipment of roadway and pedestrian parts of pavement and it is designed to regulate traffic of vehicles and pedestrians on pavement with special coating. Proposed pavement includes material applied to surface of roadway and consisting of layers of tapes placed one over the other so that extreme layers form closed space into which additional layers are placed, space being connected with main line for filling working medium. Novelty is that layers of tapes placed one over the other are made of thin-walled elastically yielding material, and two or more layers of perforated tapes are used as additional layers between which hydro-reactive heavily swelling material is filled. Used as said material is polyelectrolytic hydrogel with volumetric expansion and increase of volume at swelling not less than 2.0 x 10⁴. Water with addition of surface active substance in amount of 0.01 m.p. per 100 m.p. of water is used as working liquid for swelling of hydrogel. Invention makes it possible to provide mobile road pavement ready for use and automatically reacting to load applied by pedestrians and vehicles at sharp reduction of losses in carrying and through capacity of road pavement on protected section.

EFFECT: improved efficiency at application, reduced labor input, meeting of technical and ecological requirements to mobile pavements.
