What is the typical height of curbs in roadway design according to specifications?

• A. 4 inches
• B. 6 inches
• C. 8 inches
• D. 10 inches

Answer: (B)

In roadway design, the typical height of curbs is generally standardized around 6 inches. This height is considered effective for a variety of purposes, including channeling water runoff, providing a barrier between roadways and pedestrian paths, and ensuring that the curb is sufficient to contain water in the curb and gutter system during rainfall. A height of 6 inches is also practical for vehicle clearance, as it minimizes the risk of damage to vehicles while still serving its functions effectively. The specification of 6 inches is widely accepted in engineering practices and guidelines, as it strikes a good balance between structural integrity and functionality. Heights below this may not adequately manage stormwater runoff, and heights above it may pose challenges for vehicle and pedestrian safety. Therefore, 6 inches is the standard height used in most applications related to curb design in roadway systems.
