Geologic materials exhibit a wide range of behavioral responses following excavation and replacement in a new environment. This is a result of various mechanisms induced by variations in moisture and stress regimes or other environmental aspects of the materials. The physical disintegration of such geologic materials caused by fundamental changes in stress conditions or strength characteristics is referred to as slaking. The most distinctive aspect of the slaking process is a relatively rapid decrease in fragment size of the material. To develop an understanding of the slaking process, a comprehensive evaluation of existing data was undertaken that included a detailed literature review of geotechnical, agronomical, and geochemical test procedures used to identify potentially problematic slakable materials. The findings from this review are incorporated into a comprehensive laboratory testing program that forms the basis for a proposed classification system and spoil management program. It is concluded that a relatively simple series of tests can be used to assess the probable impact of slaking of fine-grained materials on stability, settlement, and erosion potential. Comparisons are made between laboratory and field observations to support this conclusion. (Author)
