Weathering Classes In Relation To Physical And Mechanical Properties Of Decomposed Granite

The main challenges in the study of slope stability, foundation, underground openings and excavation of rocks are by understanding the degree of weathering. The weathering profile at certain area are usually graded based on field observation, geological studies and material properties of the rocks....
