What is the correct maximum allowable slope for Type B soil?

The maximum allowable slope for Type B soil is 1:1, meaning that for every horizontal unit, the vertical rise can equal one unit. This degree of steepness is considered appropriate for Type B soils, which are typically cohesive and have a moderate ability to resist erosion and gravity forces. The 1:1 slope is often used in excavation and construction practices because it strikes a balance between safety and stability. While more stable Type A soils can support steeper slopes, Type B soils require a less severe incline to maintain their structural integrity and prevent collapse. Thus, a 1:1 slope is deemed the maximum safe angle for these types of soils. This is important knowledge when engaging in excavation and construction activities to ensure safety and compliance with engineering standards regarding soil behaviors.
