Predictability of physical changes of clay-forming materials in Oklahoma

Abstract

In cooperation with the Oklahoma Department of Highways and the Federal Highway Administration, Department of Transportation, a research project was undertaken on October 8, 1968 by the Oklahoma University Research Institute, Norman, Oklahoma to study the predictability of physical changes in clay forming materials. These materials include shale, claystones and their derivatives. The main objective of the study was to establish a systematic method of testing and criteria which will permit identification and classification of clay forming materials on the basis of the changes in their properties resulting from engineering processes associated with highway construction and utilization. The period of this study, initially approved, was three years. In March/April 1971, a request was made and approved to extend the period of study by six months. The final date of completion of this study is February 29, 1972. Reports were submitted quarterly indicating the progress of the work. Progress reports of more detailed nature were submitted annually during March/April of each year the study was in progress. In February, 1970, a special report was made on the "Disintegration of Shales Employing Ultrasonics". Much of the information contained herein has already been reported in the reports mentioned above.
