AM2 airfield matting has a long history of successful performance as an expeditionary airfield surfacing system. The U.S. Marine Corps established different lay patterns to assemble AM2 mat expanses that can be used to form aircraft operating surfaces. A program was initiated by the Naval Air Systems Command to evaluate and identify optimal AM2 lay patterns under different traffic conditions and to validate a Dynamic Interface Model with mat breakage, deformation, and recorded strain data. The efforts of the test program discussed in this report focused on evaluating an AM2 surface installed in a brickwork pattern on both a uniform subgrade surface and a subgrade with artificial voids to determine the effect of voids beneath the mat on the structural integrity of AM2.The mat surface was subjected to simulated F-15E and C-17 traffic while monitoring damage, deformation, and strain response. Premature failure was observed, but posttest investigations and analyses revealed a manufacturing error that produced a weak end connector design. This report provides test results for each evaluation and discussions comparing their performance to previous tests conducted under similar conditions.
