REINFORCING MESHY MATERIAL Russian patent published in 2015 - IPC E01C11/00 

FIELD: construction.

SUBSTANCE: invention relates to meshy reinforcing roll materials designed for creation of reinforced layers in various bitumen coatings, for instance, road, soil, asphalt ones, etc. The reinforcing meshy material comprising a coating and including crossing bundles of threads placed on a sheet non-woven material, where bundles of threads of one of crossing directions contain longer tying threads that envelope the bundles in a wave-like manner and connect them in crossing zones with bundles of threads of other crossing direction. Longer tying threads connect bundles of threads with a sheet non-woven material, bundles of threads in both directions of crossing are made as tripled from three strands of threads arranged with a gap between strands, making from 0.1 to 0.4 of the width of the appropriate bundle of threads. Longer tying threads envelope each of three strands of threads in a wave-like manner, forming a tripled bundle of threads, and each of three strands of threads forming tripled bundles of threads, not containing tying threads, is made as doubled. Impregnation and/or coating of the reinforcing meshy material is arranged by bitumen produced from water emulsion of bitumen. The reinforcing meshy material is made as perforated, besides, quantity and dimensions of perforations are determined by the area of the aerotransparent surface of the reinforcing meshy material selected on the basis of the following ratio: $$\frac{S_a}{S_t}=0,01÷0,09,$$ , where S_a - area of the aerostransparent surface of the meshy material, S_t - total area of the surface of the reinforcing meshy material.

EFFECT: improvement of filtering capacity of mesh, reduced capability of irreversible deformation and damage of a net under conditions of considerable deformations of the coating, preservation of reinforcing ability of the mesh even after significant deformations of the coating.
