Abstract: This investigation was conducted to evaluate the performance of Dow XM18·E and Alcoa AM2 landing mat. A test section consisting of a heavy-clay subgrade was constructed and surfaced with the Dow and Alcoa landing mat. The test section was subjected to traffic representing 1600 operational cycles of an aircraft having a 60,000-lb gross weight with a single-wheel main-gear assembly load of 27,000 lb and a 30-7.7 tire inflated to 400 psi. Based on the results obtained in this investigation, it is concluded that: (A.) the Dow XM18·E landing mat will sustain 1600 cycles (188 coverages) of aircraft operations with a 27,000-lb single-wheel load and 400-psi tire-inflation pressure when placed on a clay subgrade having a CBR of 3.3 or greater throughout the period of traffic; this performance meets service requirements set by the Naval Air Engineering Center (NAEC); and (B.) the Alcoa AM2 landing mat did not meet minimum test requirements set by NAEC.
