GEOGRID FOR ROAD SURFACES AND METHOD OF ITS MANUFACTURING Russian patent published in 2015 - IPC E01C3/04 

FIELD: construction.

SUBSTANCE: geogrid for a road surface is made in the form of a flat material of cellular structure formed by imposition of two mutually crossing systems of warp and weft threads with fixation of the place of their crossing. Along the warp at the distance that is larger than the cell width, but is less than the width of the vehicle tyre tread there are reinforcing threads laid with linear density increased 1.2-5.0 times, compared to the linear density of other warp threads.

EFFECT: increased strength of temporary technological soil field and along-the-highway roads due to improved structure of a reinforcing geogrid, providing for its increased stiffness and bearing capacity, with rational consumption of material for manufacturing of a geogrid.
