METHOD AND STRUCTURE OF AUTOMOBILE ROAD ERECTION WITH HARD SURFACE Russian patent published in 2009 - IPC E01C5/00 

FIELD: construction, road engineering.

SUBSTANCE: invention is related to road engineering and may be used in construction of aerodrome runways. Suggested method for erection of automobile road includes arrangement of road bed or road bed with laid lavel of crushed stone sprinkled with layer of soil, for instance, sand, on which double-rope geogrid is laid, in cells plates are installed, which have grooves in ends. Units of geogrid are located in lower part of cut angles of plates, and grid channels border plate from all sides and fully enter plate grooves along diametre. Structure of automobile road provides for the fact that in road bed or crushed stone layer sprinkled with soil there is a double-rope geogrid installed together with plates, at that double-rope geogrid has cells, in which plates are installed, in grooves of plates there are adjacent ropes of one of geogrid cells, which fully enter plate grooves along diametre, and units of geogrid cells are located at the joint of plate angles, in which lower part is cut.

EFFECT: increased bearing capacity of automobile roads with provision of smoothness and durability.
