ROAD SLAB Russian patent published in 2021 - IPC E01C5/06 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and can be used in the manufacture and reconstruction of road and airfield slabs. The road slab is made as a combined one, consisting of an upper concrete layer and a lower layer in the form of a polymer composite slab, which is fastened to the concrete layer through transverse discrete anchors in the form of protrusions or through longitudinal continuous anchors in the form of protrusions, which are fixed on the polymer composite slab and recessed into the concrete layer. Transverse discrete anchors in the form of projections are made in the form of coils or clamps. Continuous anchors in the form of protrusions are made in the form of polymer composite pipes, at least two, laid along the length of the polymer composite plate and fixed on it with clamps, while the polymer composite pipes can be made perforated.

EFFECT: road slab has increased durability and crack resistance when exposed to dynamic and alternating loads by reducing its weight.
