What is the presumptive load-bearing pressure of sandy gravel, in pounds per square foot?

  1. 1,000

  2. 2,000

  3. 3,000

  4. 4,000

The correct answer is: 3,000

The presumptive load-bearing pressure of sandy gravel is recognized as being around 3,000 pounds per square foot. This value is critical in the field of construction and structural engineering, as it provides a guideline for estimating the load that the soil can support before undergoing significant deformation or failure. Sandy gravel is generally considered a strong and stable material, making it suitable for various types of construction projects. Understanding the correct bearing pressure is essential for ensuring the safety and integrity of structures, as it helps in determining the appropriate foundation designs and depths needed for various building loads. If the soil is assessed to have a lower load-bearing capacity than what is required for the proposed structure, measures such as soil compaction, the use of deeper footings, or other ground improvement techniques may need to be implemented.
