dc.description.abstractThe test facilities and techniques described herein are being used in studies conducted at the U. S. Army Engineer Waterways Experiment Station under DA Project 1-T-0-21701-A-046, "Trafficability and Mobility Research," Task 1-T-0-21701-A-046-03, "Mobility Fundamentals and Model Studies," under the sponsorship and guidance of the Directorate of Research and Development, U. S. Army Materiel Command. Acknowledgement is made to Lt. Gen. A. G. Trudeau, former Chief of Research and Development, Department of the Army, who directed the initiation of the study of the performance of soils tmder pneumatic tires; to Mr. R. C. Kerr, chairman, and Dr. Lester Goldsmith, Dr. L. C. Stuart, Dr. Robert S. Rowe, and Mr. C. J. Nuttall, members of the ad hoc committee that recommended the research program; and to Messrs. R. R. Philippe and R. F. Jackson, U. S. Army Materiel Command, and Mr. M. V. Kreipke, Office, Chief of Research and Development, who visited the Waterways Experiment Station and advised in the formulation of the research procedures. Personnel of the Land Locomotion Laboratory, U. S. Army Tank-Automotive Center, and of the U. S. Army Transportation Research Command, both of which are under the U. S. Army Materiel Command, maintained liaison and made valuable comments and suggestions. Messrs. C. J. Nuttall and C. W. Wilson of Wilson, Nuttall, Raimond, Engineers, Inc., served as consultants and aided in the formulation of the test program, design of the test equipment, and analysis of data. Testing to determine the performance of soil under pneumatic tires has been and is being conducted by personnel of the Army Mobility Research Branch, Mobility and Environmental Division, Waterways Experiment Station, under the general supervision of Messr. W. J. Turnbull, W. G. Shockley, and S. J. Knight, and the direct supervision of Mr. D. R. Freitag. Mr. J. L. McRae directly supervised this project during a 12-month absence of Mr. Freitag, who was studying under a Research and Study Fellowship grant. Other personnel who have been actively engaged in the study are Messrs. C. J. Powell, A. B. Thompson, J. L. Smith, G. T. Easley, R. D. Wismer, G. W. Turnage, and SP-4 J. R. Wood, engineers, and Miss M. E. Smith, mathematician. This report was written by Messrs. McRae, Powell, and Wismer. Material assistance in the prosecution of the work was given by 1st Lt. L. J. Lanz, Transportation Corps Liaison Officer. Col. Edmund H. Lang, CE, and Col. Alex G. Sutton, Jr., CE, served as Directors of the Waterways Experiment Station during the preparation of this report, and Mr. J. B. Tiffany was Technical Director.en_US
