What type of soil is characterized by having little or no clay content and includes gravel, sand, or silt?

Granular soil is defined by its lack of clay content, which results in a loose structure primarily composed of larger particles such as gravel, sand, or silt. This type of soil is important in construction and excavation because it has high permeability, allowing water to drain through it easily. The individual grains in granular soil do not adhere to one another, which means that it does not behave like cohesive soils that contain clay, resulting in a greater ability to support heavy loads without significant deformation. Understanding soil types is crucial for excavators, as it impacts foundation stability, drainage, and overall site preparation for construction projects.
