The engineering classification of weathered rock mass

For a good understanding of the engineering performance of the weathered rocks, an appreciation of the degree of weathering is very important. Classified grades and zones provide a framework within which strength behaviour can be interpreted and linked to engineering performance. It has always been desired that the rock mass must be assessed quantitatively rather than qualitatively which can serve as basic input in design and analysis. In the present study an attempt has been made to study the weathering profiles and develop a rating based classification system for the assessment of weathering stages.
