Assessing the Strength and Durability Properties of Shales

Abstract

Quantitative assessment of the strength and long-term stability properties of shale slopes may be addressed via a modified slake test. The slake test measures sample weight loss following a drying, immersion, and sieving cycle. A modified test, the slake differential (SD) test, compares the results of a single-cycle test to the results following five cycles, which are assumed to be measures of the degree of weathering and rate of weathering, respectively. Such a test was completed on over 100 shale samples, representing ten geologic formation in Colorado. Interpretation of the SD test provides relative estimates of the degree of intactness of a weathered rock mass, the behavior upon exposure or reworking, and the appropriate follow-up tests for further engineering characterization.
