The initial goal was to devise an engineering classification system for intact rock samples based on simple index tests which could be used to categorize Kentucky surface and near-surface rock types and assist Kentucky Department of Transportation personnel in planning for transportation facilities. While conducting the literature survey, several facts become apparent:
- a large number of rock classification systems, geologic and technical, general and specific, already existed;
- an equally large number of index tests had been devised; and
- there was a lack of communication among those involved in specialized areas of rock-related work (geologists, civil engineers, mining engineers, etc.), and, to some extent, among individuals within each field.
It was evident from a careful study of existing classification systems and index testing procedures that developing yet another "specialized" classification system with associated index tests would not be a significant contribution. It was decided, therefore, to concentrate on development of an overall rock evaluation schema which, while useful for a specific purpose, would avoid the undesirable disparate characteristics of narrowness or over-generalization prevalent in many classification systems. It was desired also to develop the program format in such a way that accumulated information could be systematically stored for easy access and use. It was apparent that full development and implementation of a program of this nature would require years of further studies and cooperation of many individuals and organizations. Such a program, properly developed and used, would substantially contribute to an advancement and a delineation of the schema and guidelines for its implementation would be a worthy goal.
