ABSTRACT:
This invention relates to a geogrid structure which is comprised of two or more layers of rigidly bonded flexible mesh structures. The mesh openings of each layer, without superimposing, overlay mesh openings of other layers, resulting in a geogrid structure which consists of small and large sized mesh openings. The smaller sized mesh openings are designed to reduce vertical migration of the smaller aggregate particles into the subgrade and to reduce pumping of the subgrade material into the aggregate layer. The rigid bonding of multiple layers of mesh structure provides a mechanism for transmission of tensile stress which is less dependent upon interlocking of aggregate particles. Furthermore, by bonding multiple layers of mesh structure, the number of tensile elements per unit area is increased, and as a result, the interaction of the geogrid with the fill material is enhanced. This increased interaction results in enhanced interlocking of aggregate particles and in increased frictional resistance of the geogrid structure for a variety of fill material. As a result, the geogrid structure of the present invention exhibits enhanced tensile stress transmission for a spectrum of high and low grade fill material.
