CONCLUSION
The systematic assessment method and the comprehensive data analysis on
the weathered sandstone and weathered shale had been carried out to
establish their respective strength models as individual material and
composite material. Even though there is no direct laboratory works has
been carried out on composite sample the results have shown some
promising findings on the prediction of the strength behaviour of
composite sandstone and shale rock of Kenny Hill formation. The
respective empirical equations can be used either to predict the elastic
modulus, stiffness or strength indices from a simple test result as
simple as a point load strength test. In real life problem, it is very
important to the practitioner to be able to characterise and determine
the geotechnical behaviour of weathered sandstone and shale as a
composite rock mass for cost saving and safe geotechnical design.
