Mudrocks are common materials in civil engineering projects as construction materials for rock fills and embankments and in natural and undisturbed state in foundations, cut slopes, tunnel and underground spaces. These type of rocks are characterised by a wide variation in its engineering properties. The goal of this study is statistical analyses to evaluate the mudrocks data and to explore the possibility that strong predictive relationships could be developed for use in practice. A large number of tests were carried out to investigate physical and mechanical properties of different types of mudrocks. Results of different statistical analyses are presented in this paper. These results include statistical summaries and regression analyses. Good correlations exist between some index parameters and mechanical properties and a number of regression equations are proposed for predicting mechanical properties. Such correlation may be of use to civil and mining engineers, in providing preliminary estimates of mechanical properties and perhaps reduce testing requirements.
