Characterization of weathered rock for excavation work / Mohd Akmal Arif Hj Mohd Zafri

The engineering properties of weathered rock are very critical especially related to quantifying whether it is a rock, soft rock or hard material. The vast definitions of weathered rock always resulted to disputes between the practitioners, client and contractor in interpreting the rock state. Issue...
