Evaluation of XM20 and XM20E1 Landing Mats under Heavy-Duty Load

摘要

The report describes investigations conducted to evaluate two aluminum alloy landing mats. These mats were designated as XM20 and XM20E1, and they are one-piece hollow extrusions fabricated from 6061 aluminum alloy artificially aged to the T6 condition. Investigations consisted of traffic, skid, and laboratory tests to obtain information for use in evaluating the mats for potential use as heavy-duty landing mats. Traffic tests were conducted with the mats placed on a prepared subgrade and trafficked with a rolling wheel load simulating actual aircraft operations. (Author)
