SHALE CLASSIFICATION TESTS AND SYSTEMS: A COMPARATIVE STUDY
The abundance of shale rock necessitates its economical and efficient use in compacted embankments. Differing shale durabilities require a variety of design parameters and construction techniques. Classification systems for shales are available, and are helpful, but most have not been definitively correlated with field performance of compacted shales. Simple laboratory tests were selected from several existing classification systems, and performed on six Indiana shales. THe shales were then classified by each system, and the descriptive categories for the various systems were compared. Tests expected to be particularly useful in shale classification include Slake Durability and two simple slaking procedures. Tests designed to evaluate mineral aggregates for pavements were generally to severe for the softer shales which are most prevalent in Indiana.
