What is the maximum slope angle for Type C soil?

The maximum slope angle for Type C soil is established based on guidelines to ensure safety during excavation and construction activities. Type C soil is classified as loose and dry; it is typically composed of granular materials that have a lower cohesion and shear strength compared to other soil types. Therefore, the stability of slopes in Type C soil is a critical consideration.

The maximum allowable slope for Type C soil is 34 degrees, which provides a balance between safety and practicality. This angle helps to minimize the risk of soil collapse and slides, which can lead to hazards for workers in and around excavated areas. Adhering to this slope angle helps ensure that the excavation site complies with safety regulations and reduces potential accidents caused by soil failures.

Angles greater than 34 degrees would typically not be safe for Type C soil, as the likelihood of a slope failure increases dramatically, posing serious safety risks to workers and equipment. Thus, the answer reflects the best practices for managing the risks associated with this type of soil during construction activities.
