Which of the following can be included as part of dust control measures?

• A. Increased traffic speed on construction sites
• B. Proper maintenance of unpaved roads
• C. Less use of heavy equipment
• D. Maximizing vehicle cargo loads

Answer: (B)

The inclusion of proper maintenance of unpaved roads as a dust control measure is crucial because unpaved roads are a significant source of dust emissions, particularly in construction sites and rural areas. Effective maintenance can involve practices such as grading the surface to eliminate ruts and potholes, applying water or dust suppressants to keep the surface moist, and regular inspections to ensure these measures are implemented consistently. This not only minimizes dust generation but also enhances road safety and vehicle efficiency.

In contrast, the other options either do not contribute to effective dust control or could exacerbate dust problems. For example, increased traffic speed typically leads to more dust being kicked up by vehicles. Similarly, less use of heavy equipment may not directly impact dust generation unless it addresses the underlying sources of dust. Lastly, maximizing vehicle cargo loads without considering the proper securing and coverage of materials can lead to spillage and further dust emissions. Hence, the proper maintenance of unpaved roads stands out as a proactive measure to effectively manage dust generation.
