Which type of soil includes angular gravel similar to crushed rock?

The correct answer identifies Type B soil, which is characterized by being cohesive and including granular materials such as angular gravel that resembles crushed rock. This type of soil is often classified based on its identification in engineering contexts, where its properties affect excavation and construction practices.

Type B soils have moderate shear strength and are generally considered stable under many conditions, making them suitable for certain types of applications, especially in excavation and construction projects. The presence of angular gravel indicates that this soil type can support loads adequately while providing good drainage compared to finer materials. Understanding the nature of Type B soil is crucial for excavation operators, as they must assess the risks associated with the soil’s stability and choose the appropriate methods and equipment for excavation safely.

In contrast, the other soil types may consist of different materials or have varying properties that do not align with the characteristics of angular gravel or crushed rock. This distinction is important for operators to ensure compliance with safety standards and effective excavation practices.
