For Class D riprap, what is the maximum weight of the stones?

• A. 100 kgs
• B. 200 kgs
• C. 150 kgs
• D. 50 kgs

Answer: (B)

In the context of Class D riprap, the criteria for stone sizing and weight are established to ensure effective erosion control and stability along shorelines and embankments. Class D riprap is typically categorized to include stones that can withstand certain hydraulic forces while effectively dissipating energy from water flow. The maximum weight of the stones permitted for Class D riprap is crucial for maintaining the structural integrity and functionality of the installation. Stones exceeding certain weight thresholds may be prohibitively difficult to handle and install, while those that are too light may not provide adequate erosion protection. In this case, the maximum weight of 200 kgs aligns with the requirements for Class D riprap, as it provides a balance between manageability during installation and sufficient mass to resist displacement from flowing water. This specification enables the material to effectively serve its intended purpose without posing unnecessary challenges during construction.
