Abstract: This report presents a summary of trafficability studies conductedby the Waterways Experiment Station through calendar year 1955. Theses tudies were a part of Corps of Engineers Subproject 8-70-05-101, "Trafficability of Soils as Related to the Mobility of Military Vehicles," under Project 8-70-05-100, "Mobility of the Army." The subproject is divided into the following three phases Phase I, soils classification and trafficability data, includes the development of techniques and the necessary equipment for the determination of ground conditions by reconnaissance parties, and a graphic means of presentation of soil conditions to field commanders showing the relationship between vehicle mobility, soil type, soil condition, and slope. Phase II, soils trafficability predictions, includes the development of methods to correlate soil trafficability with weather data or with aerial photographs that will be sufficiently accurate to enable military planners to predict the trafficability of soils in areas without physical tests. Phase III, crossing areas of mud, sand, or other unstable terrain, includes the development of portable roadways and construction of roadways from local and other materials for crossing sand areas, canals, dikes, streams, and areas subject to inundation. Investigation of the first two phases has been assigned to the Waterways Experiment Station; phase I is the principal subject of this report. Authority for this report is contained in the Plan of Tests, Trafficability Studies, Fiscal Year 1954, approved by the Office, Chief of Engineers. The studies and field tests which form the background of this report were conducted by the Trafficability of Soils Section of the Flexible Pavement Branch, Soils Division, Waterways Experiment Station. Acknowledgment is made to the Engineer Research and Development Laboratories which was the development agency for the project until December 1950, particularly to Messrs. G. B. Schoolcraft and P. w. Woodring for their advice and planning. Messrs. R.R. Philippe, R. F. Jackson, J. W. Moss, A. R. Smith, and R. L. Tolbert and other personnel of the Engineer Research and Development Division of the Office, Chief of Engineers, furnished guidance and assistance, particularly in the various conferences held during the program. Consultants who provided valuable assistance in planning the trafficability studies reported herein included Dr. Arthur Casagrande, Dr. Donald Taylor, Professor K. B. Woods, Dr. A. A. Warlam, Mr. Robert Horonjeff, and Mr. M. P. Harrington. Personnel of the Ordnance Department, the Yuma Test Branch, Fort Churchill (Canada), Fort Knox, Fort Benning, and various other military establishments contributed equipment, services, and facilities for the field tests. Engineers of the Waterways Experiment Station actively connected with the tests and studies under phase I were Messrs. W. J. Turnbull, W. K. Boyd, C.R. Foster, O. B. Ray, S. J. Knight, R. G. Ahlvin, A. A. Rula, and D.R. Freitag. This report was written by Mr. Knight.
