Evaluation of Waterways Experiment Station Developed Aluminum Access/Egress Modules.
Abstract
This investigation was conducted to determine if a hinged-aluminum panel system, extruded aluminum access/egress surfacing module, would provide exit roadways out of rivers for fording/swimming vehicles, access lanes for bridge or raft launching equipment, and roadways to and from a bridgehead. Studies were also conducted to determine module placement procedures and the compatibility of the modules with the access/egress roadway system dispenser. The surfacing modules were placed on a low-strength soil test section, and military vehicles were trafficked on the modules to determine if they would support 3,000 passes of mixed military vehicle traffic. The surfacing was then placed on a 25 percent slope and trafficked with wheeled and tracked vehicles during dry, wet, and muddy conditions to determine the traction characteristics of the modules. Twenty-five passes of an M113 Armored Personnel Carrier were applied to a lake bank test site surfaced with the modules to determine if they would satisfy the assault egress vehicle role. Two widths of the surfacing modules were investigated to fulfill the requirements of the Letter of Agreement (LOA), each with its own method of dispensing. As a result of this investigation, the surfacing modules met the requirements for trafficking and dispensing as stated in the LOA. However, several recommendations to further improve the system are included based on the findings reported herein. (Author)
