If the soil has a compressive strength of .05 tsf or less, it is classified as what type?

• A. Type A
• B. Type B
• C. Type C
• D. Type D

Answer: (B)

The classification of soil based on its compressive strength is essential in understanding its suitability for construction and excavation projects. A soil with a compressive strength of 0.05 tsf (tons per square foot) or less falls into the Type B category. This classification indicates that the soil has moderate stability and can support some loads, but it is not as strong as Type A soils, which have higher compressive strengths. Type B soils typically include cohesive soils like clay and silt that can show some strength under certain conditions but may also exhibit instability when saturated or subjected to excess loading. It is crucial to recognize this because excavation practices and safety procedures differ based on the soil type, and understanding these classifications assists in planning and implementing proper excavation techniques to prevent collapses and ensure worker safety.
