Abstract

One of the most important challenges in the study of slope stability, foundation, and excavation in rocks is understanding the weathering states. This issue is more important in tropical climates, where severe weathering produces thick weathering profiles. Thick weathering profiles are normally classified or graded differently based on some field observations, geological studies, and material properties of rock. This paper considers the relationship between joint characterization and the state of weathering of granitic rock as an important factor to describe the mass weathering. A total of 24 panels of rock exposures was studied in two active granite quarries located in Johor, Malaysia. This region has a tropical climate condition. A typical profile was proposed for granitic rock, mainly based on joint characterization, topography, and geological condition. This profile includes a common weathering ranging from fresh rock to residual soil. Based on the presence of corestones, two additional subgrades were introduced in completely and highly weathered zones. It is believed that the proposed weathering profile may contribute to engineering design and classification of weathered granitic rock in tropical region.
