Slab Thickness in Sidewalk Construction

How thick are the slabs typically used for sidewalks in simple slab on grade construction?

A. 2 to 4 inches

B. 4 to 6 inches

C. 6 to 8 inches

D. 8 to 10 inches

Answer:

B. 4 to 6 inches

In simple slab on grade construction, the slabs used for sidewalks are typically around 4 to 6 inches thick. This thickness provides enough strength and durability to withstand the load and traffic from pedestrians. The exact thickness may vary based on factors such as climate, soil condition, and the intended use of the sidewalk.

It is essential to determine the appropriate thickness of the slab to ensure that it can support the expected loads and maintain its integrity over time. Factors like soil stability and the frequency of use should also be considered when designing sidewalks to ensure their longevity.

By using slabs that are 4 to 6 inches thick, construction professionals can create sidewalks that are both functional and durable, providing safe pathways for pedestrians for years to come.
