Book Description
The investigation was conducted to evaluate three-piece AM2 landing mat. The mat was fabricated from three 8-in.-wide extrusions welded together to form a 2-ft-wide plank. A test section consisting of one sand item and three clay subgrade items with various CBR strength values was constructed and surfaced with the three-piece mat. The test section was subjected to uniform-coverage and single-line traffic representing operations of an aircraft having a 60,000-lb gross weight with a single-wheel main gear assembly load of 27,000 lb with a 30.7.7 tire inflated to 400 psi.

Book Description
This investigation was conducted to evaluate a modified and connector on the AM2 landing mat fabricated by Harvey Aluminum, Inc., Torrance, Calif. A test section, consisting of three clay subgrade items with different strengths and one sand item, was constructed and surfaced with the modified AM2 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.

Book Description
This investigation was conducted to determine the optimum panel size for the AM2 mat fabricated by Harvey Aluminum Company, Torrance, Calif. The basic AM2 mat was designed to sustain 1600 operational cycles of an aircraft having a gross weight of 60,000 lb with a single-wheel main-gear-assembly load of 27,000 lb and a 30-7.7 tire inflated to 400 psi. A test section consisting of three items with different subgrade strengths and surfaced with three different size mat panels was constructed and subjected to 188 coverages (equivalent to 1600 cycles of aircraft operations) of accelerated traffic of a 27,000-lb single-wheel load with a 30-7.7 tire inflated to 400 pri. The mat was also tested for its ability to sustain 1600 passes of a 39,000-lb single-wheel load applied in a single track to represent the calculated loading that would be imposed on a landing mat during launching of a 60,000-lb aircraft by catapult.

Book Description
This investigation was conducted to evaluate the new-profile AM2 landing mat, which was extruded and fabricated by Harvey Aluminum Company, Torrance, Calif. Three methods were used to attach end connectors to the 2-ft-wide main extrusion to form either the 2- by 12-ft or 2- by 6-ft planks. These methods were electron beam welded with inserts (EBI), electron beam welded without inserts (EB), and metal-inert-gas fusion welded without inserts (MIG). Two test sections, each consisting of two clay subgrade items at a strength of 4 CBR, were constructed and surfaced with the new-profile mat. Items 1 and 2 of test section 1 were surfaced with the EBI and EB mat, respectively. Both items in test section 2 were surfaced with the MIG welded mat, where two mat laying patterns were used so that the traffic lane in item 1 did not include any end joints and the traffic lane in item 2 incorporated 20 end joints. Each test section was subjected to uniform-coverage traffic representing operations of an aircraft having a 60,000-lb gross weight with a single-wheel main-gear assembly load of 27,000 lb with a 30x7.7 tire inflated to 400 psi.
