1. Road surface

A road surface (also called pavement) is the top layer of a road that vehicles and pedestrians travel on. It is designed to provide a smooth, durable, and safe surface for transportation.

  • Causes of Uneven Surfaces:
    • Roadwork or resurfacing in progress.
    • Potholes, cracks, or patchwork repairs.
    • Sunken manholes or drains.
    • Frost heave (caused by freezing and thawing).
    • Tree roots pushing through pavement.
    • Erosion or shifting ground.
  • How It Affects Driving:
    • Reduces vehicle stability.
    • Can cause bouncing or jolting.
    • May damage tires, suspension, or alignment.
    • Can make steering or braking more difficult.
