'integral geogrid made from a coextruded multilayer polymeric starting material, and a method of fabricating such integral geogrid?'

摘要

integral geogrid comprising a plurality of oriented and interconnected wires having an array of openings therein which is produced from a coextruded multilayer polymer sheet starting material. By virtue of their construction, coextruded multilayer sheet components provide a crystalline synergistic effect during extrusion and integral geogrid orientation, resulting in improved material properties that provide performance benefits to the use of integral geogrid in geosynthetic soil reinforcement.
