GEOGRID FOR REINFORCEMENT OF BASE LAYERS AND ROAD PAVEMENT Russian patent published in 2024 - IPC E02D17/20 

FIELD: transport construction.

SUBSTANCE: invention relates to the field of transport construction, namely to reinforcing layers in the form of geogrids, intended for increasing durability of road pavement. Geogrid for reinforcement of layers of base and pavement is a configuration of cells forming a hexagon by intersection of ribs. Cross-section of central ribs is made in the form of isosceles trapezoid, and extreme ribs – in the form of rectangular trapezoid, with its smaller base directed to the reinforced layer. Nodal connections are reinforced with cylinder-taper elements, besides, angular cylinder-taper elements have through holes in which anchors are installed with possibility of removal.

EFFECT: providing creation of geogrid for reinforcement of road pavement, having high strength of nodal connections and attachment of adjacent geogrids to each other.
