· Soft Rock and Shale Embankments. In embankments composed of rock fill with rocks that weather quickly, there is a potential for the rocks to become soil. As a consequence, these materials could fall into the spaces between the rocks — leading to significant settlement of the embankment, and ultimately, slope failure. It is for this reason that shale is not recommended; large pieces of shale ...
