Abstract:
A geosynthetic material for reinforcing a soil material to form a reinforced soil composite, the geosynthetic material comprising:(a) a first plurality of spaced-apart generally parallel fiber strands, wherein the first plurality of fiber strands includes fibers coated with an essentially dried residue of a first sizing composition and a first base coating composition comprising film-forming materials applied over the first sizing composition such that at least a portion of the first plurality of fiber strands are impregnated with the first base coating composition, and further wherein at least a portion of the first plurality of fiber strands comprises glass fibers;(b) a second plurality of spaced-apart generally parallel fiber strands positioned adjacent to and forming a plurality of intersections with at least a portion of the first plurality of strands, wherein the second plurality of fiber strands includes fibers coated with an essentially dried residue of a second sizing composition and a second base coating composition comprising film-forming materials applied over the second sizing composition such that at least a portion of the second plurality of fiber strands are impregnated with the second base coating composition, and further wherein at least a portion of the second plurality of fiber strands comprise glass fibers;(c) a first tying member fixedly connecting portions of fiber strands of the first plurality of fiber strands with intersecting corresponding portions of the second plurality of fiber strands;(d) a second tying member fixedly connecting at least two adjacent generally parallel spaced fiber strands of the first plurality of fiber strands; and(e) a bonding agent adhering predetermined regions of selected fiber strands of the first plurality of fiber strands with predetermined regions of selected fiber strands of the second plurality of fiber strands, wherein the bonding agent is applied over selected portions of the first and second base coating compositions,wherein the geosynthetic material resists chemical and biological attack from soil material.
