This Summary of Progress is a compilation of information on all projects initiated under the National Cooperative Highway Research Program (NCHRP) from its inception in 1962 through 1988. Annually, for 27 years, the NCHRP has issued a Summary of Progress comprised of up-to-date status reports on all on-going projects and brief statements on those that have been completed. Future summaries will not contain the completed projects that are found in this volume, which is the last complete source of information on all NCHRP projects. Subsequent editions will update the Summary of Progress series, including only projects active after January 1, 1989. The contents of this edition are as follows: introduction; how NCHRP programs are formulated; programs received to date; financing the program; how the NCHRP is organized to administer research programs; how the projects are placed under contract; keeping track of research in progress; systematic planning for getting research results from NCHRP projects into practice; implementing research results; examples of utilization of NCHRP research results; award-winning research under NCHRP; summary; and progress by project for the twenty-five subject area categories. |
