METHOD AND DESIGN OF MOTOR ROAD CONSTRUCTION AND REPAIR WITH HARD RUT-PROTECTED COATING Russian patent published in 2011 - IPC E01C5/06 E01C23/06 

FIELD: construction.

SUBSTANCE: in method of motor road construction and repair with hard rut-protected coating, rut-protected slabs, solid or with holes, are laid onto the road bed partially filled to a design elevation in an addressed manner, as well as additional slabs made of inert material with reinforcement or without it, which are then filled with the road bed material to the design elevation of the road bed top, onto which the hard coating is laid, and during motor road repair, the road hard surface lane with formed ruts and adjacent sections is cut together with a part of the road bed to the depth of the addressed installation of the rut-protected and additional slabs, after installation of which onto the cut bottom it is filled with the road bed material, on which the hard coating is laid, besides, the rut-protected slabs are made of inert material with reinforcement or without. Design of the motor road with hard rut-protected coating, the rut-protected slabs have fixed width and are laid into the road bed body in an addressed manner at a certain depth from the road surface, at side edges the rut-protected slabs have ledges, and instead of the rut-protected slabs ledges it is possible to use additional slabs, which have dimensions of ledges laid next to the rut-protected slabs and in a staggered order between each other at the distance from 0.1 to 0.3 m.

EFFECT: reduced chances for ruts formation.
