The investigation was conducted to evaluate an extruded aluminum alloy landing mat (designated XM180). The mat is a one-piece extrusion fabricated from 6061 aluminum alloy artificially aged to the T6 condition. The mat panels are interlocked along the sides by means of a hinge-type connector, the components of which are an integral part of the basic panel extrusion. End connectors, composed of extruded connectors welded to the basic panel, consist of overlap and underlap sections secured by a locking bar after individual panels have been joined together. The mat mentioned herein was different from modified MX18-B mat in that the inserted tubes in the ends of the mat panels were shortened by 3/4 in. and the amount of metal was increased in the area of the female connector and first cavity adjacent to this connector. The method of attaching the end connectors to the mat extrusion was changed to allow improved welds at the corners. The investigation consisted of traffic, skid, cable roll-over, and laboratory tests to obtain information for use in evaluating the XM180Q mat for potential use as a medium-duty landing mat. The test data reported herein were evauated against the criteria for medium-duty mat as established in the revised Qualitative Materiel Requirement (QMR).
