This study was conducted to develop a CBR design curve for subgrades to be surfaced with M9M1 landing mat to withstand 1600 taxiing cycles of an aircraft with a 17,000-lb single-wheel load on a 30-7.7 tire inflated to 400 psi. A test section consisting of several items with different subgrade strengths (CBR ranging from 9 to 65) and surfaced with the M9M1 landing mat was constructed and subjected to accelerated traffic of a 17,000-lb single-wheel load with a 26-6.6 tire inflated to 400 psi. (A 30-7.7 tire was not available at the time of the tests, and the 26-6.6 tire, which constitutes a more severe test condition, was used.)
