METHOD TO CONSTRUCT AND STRENGTHEN MOTOR ROADS Russian patent published in 2013 - IPC E01C3/04 

FIELD: construction.

SUBSTANCE: method to construct and strengthen motor roads includes development of a multi-layer heterogeneous structure of a road surface by means of preparation of an underlying surface: installation of reinforcement in the road bed, pouring of concrete onto reinforcement, cover with the road mesh, fixation of the road mesh and the reinforcement, covering with asphalt concrete. The underlying surface is tilled with a plough with a plough point, harrowed, stubble is removed, the earth bed of the road surface is compacted, the earth bed of the road surface is profiled along tracks and at the edges of the road surface, the tracks are rolled by depth, which is more by at least 30% than the common thickness of the concrete layer of the surface, and at the edges of the road surface a rolled strip is arranged with depth for the half of the common thickness of the concrete layer of the surface. Then reinforcement is laid into track and edge strips of grooves in the earth bed of the road surface. Afterwards the reinforcement is placed on top along the entire width of the road surface and is fixed to reinforcement in track and edge grooves, concrete is poured, afterwards onto loops of the installed reinforcement that protrude above the concrete by 2/3 of the asphalt concrete layer thickness the road mesh is fixed, then porous asphalt concrete is laid onto the road mesh, rolled with light rollers, sealed with penetrating hydrophobic compounds, and high-strength and wear-resistant asphalt concrete is laid.

EFFECT: expansion of operational capabilities due to reinforcement of road bed and surface body and production of a pseudohomogeneous structure.
