Technical Note

2021-9-16 · As stated in AS 2758.6, larger rocks, greater than 10 tonnes have been used before but the rock mass defects within these large boulders tends to be the limiting size factor in most cases. Mostly, rocks of 10 tonne mass and less are normal for armourstone. This section discusses the range of grading requirements and is based on weight ratios.

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.
