Soil Classification
Soil Classification is a standardized way of identifying and categorizing different types of soil for construction and excavation work. It's like a system for understanding what kind of ground workers are dealing with, similar to how restaurants grade meat quality. Workers use this knowledge to determine how to safely dig foundations, build structures, or operate heavy machinery. Without proper soil classification, construction projects could face safety risks or structural problems. Common systems include USCS (Unified Soil Classification System) and AASHTO, which are like universal languages for describing soil types across the construction industry.
