  • Abstract:
    The Federal Highway Administration's (FHWA's) Geotechnical Research Program was formally initiated in the 1970s. During the early 1970s, FHWA field personnel and the State Highway Agencies recognized the need for more definitive technology for solving various soil and foundation problems. This fact, along with the stimulus of sympathetic management and funds for research, permitted the establishment of the geotechnical research program. The purpose of this report is to synopsize the program, highlighting some of the more significant findings and contributions. This report gives an overview and summarizes the results of three geotechnical research programs. The project or program areas were: soil and rock behavior, bridge foundations, and ground improvement techniques. A fourth program area, tunneling, is outside of the research reported here and is covered elsewhere. A fifth category, summarized here, included important miscellaneous studies that did not fit categories given above. The report presents narratives and a comprehensive reference list for the various research categories. Items covered, for example in foundation engineering, include pile foundations, pile groups, drilled shafts, spread footings, and foundation load testing. Ground improvement efforts and soil and rock behavior are also given in appropriate detail. Outputs, including guidelines and implementation items, are given for the various topics covered. Finally, an outline of future geotechnical research needs is presented.
