Chapter 4 Engineering Classification of Rock Materials

To use rock in engineering applications, certain prop-erties of the rock must be assessed to reasonably pre-dict performance in the as-built condition. The proper-ties of rock fall into two broad classes: rock material properties relating to the rock itself and rock mass properties relating to the in-place rock mass, including its discontinuities.
