Book excerpt: Accelerated traffic tests, which simulated aircraft taxiing operations, were conducted on test sections constructed on subgrades of various strengths and surfaced with M8A1 (formerly T10) steel landing mat. The purpose of the tests was to obtain data on the service life of the M8A1 mat under various conditions of wheel load, tire pressure, and subgrade strength. From these data, CBR design curves for runways surfaced with M8A1 mat, similar to CBR design curves for bituminous pavements, have been developed. Operations of military aircraft with single-wheel loads ranging from 25,000 to 50,000 lb and tire pressures ranging from 60 to 300 psi and aircraft with twin-wheel assembly loads of 50,000 lb were simulated by means of a test load cart. CBR, water content, and density of the subgrade were measured before and during the traffic tests, and the condition of the test sections was recorded. Traffic was applied until the test sections failed or until it was evident that 700 coverages could be completed by the test load cart. The design curves, which were developed by correlating the M8A1 test data with flexible pavement design relations, are considered adequate for use in designing landing strips to be surfaced with M8A1 steel landing mat.

This book was released on 1964 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation was conducted to develop a CBR design curve for modified AM1 landing mat fabricated by Butler Manufacturing Company, Kansas City, Missouri. The design curve was to indicate the subgrade strength required, when the subgrade is surfaced with the modified Butler AM1 mat, to withstand 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 30.00-7.7 tire inflated to 400 psi. It was also desired to test the modified AM1 mat fabricated by Fenestra, Inc., Philadelphia, Pennsylvania, in order to obtain comparative data. (Author).

Book excerpt: The initial phase of the study was conducted to evaluate four experimental, aluminum landing mats, and to develop CBR design curves for the one selected as most satisfactory, which was standardized and designated by the Navy as Airfield Matting No. 1 (AM1). For the second phase of the study, a production quantity of the AM1 mat was manufactured and subjected to the same types of field tests used for the experimental mats on subgrades with CBR's ranging from about 5 to 16.

Available in PDF, EPUB and Kindle. Book excerpt: The report describes a study conducted to develop CBR design curves for an aluminum landing mat. The design curves were to represent 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. CBR design curves were also desired for 1600 passes of a 39,000-lb single- wheel load applied in a single track to represent the calculated loading imposed on the landing mat during launching of the 60,000-lb aircraft by catapult.
