      A Quarter Century of Geotechnical Research   Foreword This report summarizes Federal Highway Administration (FHWA) geotechnical 
    
    
    
    research and development activities during the past 25 years. The report 
    
    
    
    includes significant accomplishments in the areas of bridge foundations, 
    
    
    
    ground improvement, and soil and rock behavior. A fourth category included 
    
    
    
    important miscellaneous efforts that did not fit the areas mentioned. 
    
    
    
    The report will be useful to researchers and practitioners in geotechnology.  **NOTICE** -  *This document is disseminated under the sponsorship of the

    Administration (FHWA) to manage the Geotechnology Research Program described 
    
    
    
    in this report. The program has benefitted from the efforts of a wide range 
    
    
    
    of FHWA personnel who contributed to the success of this program. In the beginning, 
    
    
    
    the guidance and support of Dr. Charles Scheffey and Richard E. Hay were very 
    
    
    
    helpful in establishing the program and got it going in the right direction. 
    
    
    
    I am especially grateful to Carl Ealy, who has been with me from the beginning 
    
    
    
    to the present, and deserves most of the credit for managing the deep foundations 
    
    
    
    research project. I also appreciate the contributions of Mike Adams, who has 
    
    
    
    managed the shallow foundations project and many of the ground improvement studies 
    
    
    
    during the second half of this program. Special thanks are extended to other FHWA personnel who have also contributed 
    
    
    
    to the success of this program. There are too many to mention them all by name, 
    
    
    
    but a few stand out above the rest. In the Headquarters office, Jerry DiMaggio 
    
    
    
    and Dick Cheney have provided advice concerning which topics needed to be researched, 
    
    
    
    and critiqued the work on many of the studies from start to finish. They have 
    
    
    
    used many of the results to prepare design and construction guideline manuals, 
    
    
    
    technical advisories, and engineering circulars that have been distributed to 
    
    
    
    FHWA and State Highway practitioners all over the United States and many foreign 
    
    
    
    countries. Special credit is due John Hooks and Chien Tan Chang for their efforts to promote 
    
    
    
    the technology transfer and implementation of the R&D products from this 
    
    
    
    program. They provided the resources to enable Cheney and DiMaggio to accomplish 
    
    
    
    their goals to bring the research results to fruition. The author is also indebted 
    
    
    
    to all of the Regional Geotechnical Engineers who actively supported the program, 
    
    
    
    especially Barry Berkovitz (Atlanta), Ron Chassie (Portland), Andy Munoz (Dallas), 
    
    
    
    and Barry Siel (Denver). There is considerable satisfaction in knowing that 
    
    
    
    these outstanding field engineers have taken our research products and used 
    
    
    
    them to help make roads better in their regions. The single most important person in the success of this program was Don Fohs, 
    
    
    
    who, like Chuck Scheffey and Dick Hay, is now retired from FHWA. The author 
    
    
    
    is very grateful for his support and guidance throughout the entire period of 
    
    
    
    performance. Sincere appreciation is also extended to all of the contract researchers and 
    
    
    
    organizations that participated in this program. It would be nice 
    
    
    
    to list them all by name; however, FHWA report processing requirements 
    
    
    
    prohibit the mention of contractors names in the report. This research 
    
    
    
    program was blessed with many good contract personnel. Finally, 
    
    
    
    many thanks to Raghu Satyanarayana, Clay Ormsby, Nanda Sen, and 
    
    
    
    Robin Collins for helping to prepare the manuscript.
