Which material category is described as including gravel, sand, and clay mixtures?

• A. Pipe Bedding
• B. Manhole Testing
• C. Access and Egress
• D. Pipe Deflection

Answer: (A)

The main concept here is understanding what supports a pipe during and after installation. Pipe bedding refers to the layer of material placed under and around the pipe to provide a stable, even foundation, distribute loads, and prevent settlement. This category commonly includes granular materials like gravel and sand, and clay mixtures used in some settings to achieve proper compaction and stability. That’s why it’s the best fit for a description that includes gravel, sand, and clay mixtures. The other terms relate to testing, safe access, or how much a pipe can bend under load, rather than the materials used to support the pipe.
