BUILDING METHOD AND PREFABRICATED PAVEMENT STRUCTURE Russian patent published in 2010 - IPC E01C5/08 

FIELD: building.

SUBSTANCE: in building method for prefabricated pavements, involving placement of prestressed right-angled or square reinforced-concrete slabs on a ground, sand or other base, fastening of the slabs together in one or two mutually perpendicular directions by means of through armature in openings to be tensed thereafter, sealing of joints between the slabs with an air-tight material, paving of the concrete base with asphalt or poured asphalt concrete. The slabs are fastened by packing five to twenty slabs with steel ropes thereafter to be tensed at the effort 5 to 30 "те" per each rope. Herewith between end faces of the slabs, the ropes are covered with resilient members. The steel ropes are placed in the through openings, while their ends having been fixed are anchored within fastening cavities of the slabs last in the packages with concreting the cavities. In the prefabricated pavement structure, the steel ropes are located in the through openings at the distance 0.7-2 m from each other at length of the packing openings 15 to 60 metres, with concreting the fastening cavities for the anchors and ends of the steel ropes. The slab joint dimensions are 15 to 40 mm.

EFFECT: higher maintainability of the pavement.
