METHOD OF STABILIZING TEMPERATURE MODE OF ROAD SURFACE AND ROADWAY OF BRIDGE STRUCTURE Russian patent published in 2024 - IPC E01C11/24 E01D19/12 

FIELD: bridge building.

SUBSTANCE: proposed invention relates to the field of bridge construction, namely to methods of stabilizing the temperature mode of bridge structures. Method of stabilization of temperature conditions of road surface and roadway of bridge structure consists in insulation of underbridge zone, zone of sidewalks and roadway zone. Wherein 30 to 150 mm thick foamed polystyrene plates are glued in the underbridge zone and fixed by plastic dowels with a flat nail. After complete setting, the bottom layer of concrete is formed. Further, the pavement zone and, if necessary, the roadway on the outer side of the bridge structure are insulated. At the same time a heating cable is installed, besides, the layout pitch is calculated taking into account the required temperature mode, but not more than 200 mm. After the cable is laid, a transformer substation is installed. In the area of the transformer substation, an alternative electric energy accumulation system is installed in the form of solar panels for alternative power supply of the heating cable. Finally, the area with the laid heating cable is concreted and the road surface is arranged.

EFFECT: prevention of bridge structure freezing.
