Which materials are commonly used for traction enhancement on icy roads?

• A. Sand and cinders
• B. Gravel and soil
• C. Salt and water
• D. Oil and fats

Answer: (A)

The use of sand and cinders for traction enhancement on icy roads is highly effective due to their physical properties. Sand provides texture and grit, which helps to create friction between vehicle tires and the icy surface, reducing the likelihood of slipping. Cinders, which are often derived from burned coal or wood, have a similar function; their rough surface aids in traction while being less likely to damage the roadway as some other materials might. In addition to their traction benefits, both sand and cinders do not significantly alter the road's chemical composition, making them environmentally friendly options compared to other materials. Their use is particularly advantageous when temperatures are low enough that other practices, such as the application of salt, may not be as effective. This combination of effectiveness, availability, and minimal environmental impact makes sand and cinders a preferred choice for managing icy conditions on roads.
