STRUCTURE AND CONSTRUCTION METHOD OF MOTOR ROADS Russian patent published in 2009 - IPC E01C21/00 

FIELD: civil engineering.

SUBSTANCE: invention relates to civil engineering field and can be used while arrangement of structure of motor roads. Road structure contains geotextile fabric 1, road bed 2, road metal layer 3, clutches of geotextile 4, layer of asphaltic macadam 5, herewith geotextile fabric envelopes road bed 2 and road metal layer 3 by closed shell. It provides ability at compaction to densify layers of road metal and road bed. In proposed structure geotextile fabric 1 can be laid by individual road beds connected by lockers 4, furthermore, for durability increasing of joining lockers are broached by studs, and for roads of high wigth it is provided application of geotextile with anchor clamps and absence of shell made of geotextile in the basis of roads. Stud from one side allows flat head thrusting into asphalt concrete, and from the other side pointed head, which broaches locker and is kept by projection up to falling-out before laying of asphalt concrete. Construction method of road structure consists in that on prepared by height marks section it is laid geotextile two-three times (depending on height of road bed) exceeding width of road bed, then it is constructed road bed, it is laid road metal layer and projecting edges of geotextile on each side of road is wrapped over road metal, it is connected into locker, saturated by bitumen or other binder and over it is laid asphalt concrete. While wrapping of geotextile sides it is simultaneously wrapped geotextile by butts of road, forming from it closed shell. In case of need, into lockers there are installed studs and applied geotextile fabric with anchor clamps for saving of geotextile in the basis of road.

EFFECT: increasing of load-carrying ability of motor road.
