ROAD SURFACE Russian patent published in 2021 - IPC E01C5/08 

FIELD: construction.

SUBSTANCE: invention relates to the construction of highways, airfield strips, railway foundations, cargo areas for various purposes and large-tonnage carrying capacity on soft soils. The road surface is made of rectangular reinforced concrete slabs of length (L) and width (H), laid in rows along the roadway on a road base made of reinforced concrete elements. Reinforced concrete base elements are slabs of the same shape and size as pavement slabs. Base slabs 2 are laid in parallel rows along the roadway, and their total width determines the width of the road base. Slabs 1 of the road surface are laid on top of the road base with an offset relative to the slabs 2 of the road base by half the length (L) and width (H) of these slabs 2 of the road base. In the middle of the lateral sides of the road base plates and the road surface, there are connecting elements 3 designed to ensure the connection of both adjacent road base plates and the road surface, and the road base plates and the road surface with each other.

EFFECT: reduced load per unit of base area.
