Abstract:The Federal Highway Administration sponsored an evaluation of in-situ site investigation techniques in the Forest Glen (Maryland) Field Research Experiment. Fourteen different organizations participated in the experiment using three general approaches (1) Acoustic and seismic techniques, (2) electromagnetic survey techniques, and (3) mechanical techniques. Nine of these organizations submitted written research reports. Edited versions of all but one of the reports submitted are presented in the appendices to this document. The missing submitted report contained data in the form of colored photographs which, unfortunately could not satisfactorily be presented in a black and white document. A conference documenting some of the results from this experiment was held in March 1978, in Alexandria, Virginia. The proceedings of this conference are contained in a previously published report, FHWA-TS-79-221. The results of acoustic and seismic tests by five different organizations indicated that two investigation techniques provided satisfactory results. Results from three promising results. Finally, the mechanical devices used in this study, the pressuremeter and borehole jack, can be used effectively in proper geologic setting.
