Preventing Dirt and Gravel Accumulation on Roads

How can dirt and gravel accumulation on roads be prevented?

Options:

A. By installing proper drainage systems

B. By conducting regular road maintenance

Answer:

Dirt and gravel accumulation on roads can be prevented by both installing proper drainage systems and conducting regular road maintenance.

Dirt and gravel usually accumulate at the sides or edges of roads due to factors like erosion, runoff, wind, and vehicle movement. However, the pattern of collection can vary based on the terrain. Road maintenance efforts often aim to prevent excessive accumulation.

Explanation: Dirt and gravel usually collect at the edges or sides of the roads. This is due to various factors like erosion, water runoff, wind, and the movement of vehicles. When vehicles drive on the road, their motion tends to push dirt and gravel to the sides. Particularly in unpaved roads, these materials can accumulate, forming ridges or embankments.

In more diverse terrain, the pattern of accumulation can be affected by the nature of the landscape. For instance, in hilly or mountainous areas, dirt and gravel may accumulate at the lower sides of the road. Similarly, in regions with swamps, dirt and gravel may not gather at predictable locations because the wet and marshy conditions may cause the materials to be more evenly distributed or sink into the swampy ground.

Despite these tendencies, it's important to note that local authorities who maintain roads often attempt to reduce excessive accumulation of dirt and gravel at specific parts of the roads as it can create hazardous driving conditions.
