ROAD PAD WITH COMPOSITE PAVEMENT Russian patent published in 2023 - IPC E01C7/00 

FIELD: road and airfield construction.

SUBSTANCE: invention can be used in the improvement of cities, in storage and port areas, in the installation of floors of industrial enterprises. The solution of the stated technical problem is achieved by the fact that the cement concrete layer in pavement with a composite road surface consisting of asphalt concrete and cement concrete layers is made in the form of fragmented cuts into hexagonal bearing elements, thus forming cut-grooves of the cement concrete layer, and the asphalt concrete layer is located on top of the cement concrete layer and fills the cut-grooves of the cement-concrete layer forming tongue-and-groove protrusions, while creating a single composite road surface.

EFFECT: increased uniform deformation and crack resistance of the upper asphalt concrete layer necessary for conditions of heavy and high-speed traffic and cyclical effects of natural and climatic factors, ensuring rut resistance of the pavement and durability of the road pavement.
