Abstract: The U.S. Army and Marine Corps have initiated a search for a temporary non-liquid method of mitigating dust on helipads. Past research has shown the most effective non-liquid methods consist of polymeric materials such as polypropylene woven geotextiles, polypropylene woven mesh, and polyethylene geomembranes. The purpose of this investigation was to evaluate the durability of various commercially available polymeric products along with the components necessary to connect and anchor the polymeric material to the surface. A secondary purpose was to evaluate internal connectors, installation equipment, and helipad anchoring systems. Each polymeric pad was subjected to Medium Tactical Vehicle Replacement (MTVR) trafficking patterns, which consisted of multiple passes, brake tests, and spiral turns. Instrumented anchors were installed along the perimeter of the pads to record the loads applied by the three trafficking patterns. Conclusions from each traffic test are listed, and recommendations are provided for further evaluation of polymeric helipads under actual rotary wing aircraft traffic.
