Nov 05, 2018 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

Sep 02, 2019 When stone is processed in mobile primary crushing plants, excavators or wheel loaders feed the rock into the crusher that is set up at the quarry face, gravel pit or in a recycling yard or demolition site.
