The investigation was conducted to evaluate the performance of the 1- and 2-ft-wide Harvey nonwelded aluminum landing mats and to compare the performance with that obtained in previous tests on standard AM2 mat. This landing mat was extruded by the Harvey Aluminum Co., Torrance, Calif. Three test sections were built and surfaced with different shipments or types of Harvey mat. The first and second sections were surfaced with 1- by 6-ft and 2- by 6-ft mat, respectively, each over two clay subgrade items with different CBR strength values. The third section consisted of two items surfaced with 2- by 12-ft and modified 2- by 12-ft mat over a subgrade of the same nominal strength as the lower subgrade strength of the first and second sections. All three test sections were subjected to uniform-coverage traffic, and section one was also subjected to single-line traffic. The traffic represented 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.
