Chapter 4 Engineering Classification of Rock Materials

particle size, texture, hardness, and strength. Seismic velocity, weathering, and secondary cavities are prop-erties related to both the rock material and mass. Rock material properties can be described in the field using qualitative methods and simple classification tests, or, if necessary, in the laboratory using standardized tests.
