Kerbs in the road

Kerbs, or curbs, might seem like small details in road construction, but they play a big role in how roads function and look. If you’re new to the industry, here’s what you need to know about kerbs.

What Are Kerbs?

Kerbs are the raised edges along roads, usually made of concrete, stone, or asphalt. They separate the road from sidewalks, grass areas, or bike lanes, making roads safer and more organised.

Why Are Kerbs Important?

1. Safety: Kerbs create clear boundaries between vehicles and pedestrians.

2. Drainage: They guide rainwater into drains, preventing water from pooling on roads.

3. Support: Kerbs reinforce the edges of the road to reduce wear and tear.

4. Traffic Control: They help guide vehicles and prevent them from entering restricted areas.

5. Appearance: Kerbs enhance the overall look of streets, especially in cities.

Common Types of Kerbs

1. Mountable Kerbs: Low and sloped, letting vehicles climb over when needed. Found near driveways and roundabouts.

2. Barrier Kerbs: Tall and steep to prevent vehicles from leaving the road. Used in risky areas.

3. Flush Kerbs: Level with the road surface, often used for bikes or pedestrian zones.

4. Dished Kerbs: Sloped kerbs for wheelchair and stroller access, often seen at crossings.

Kerbs in Modern Construction

Kerbs are vital in urban planning. They mark parking areas, bus stops, and loading zones, while also helping with landscaping and water drainage. New designs, like kerbs with LED lights or better drainage, are making roads safer and more efficient.

Challenges to Consider

Traditional kerbs can be obstacles for people with disabilities. To address this, modern designs focus on ramps, tactile paving for visually impaired users, and smooth transitions for cyclists.

Looking Ahead

As cities grow, kerb designs will evolve to support new technologies like autonomous vehicles and manage new traffic types. Thoughtful kerb planning will remain essential for safe, sustainable roads. Kerbs might seem simple, but they’re a critical part of road construction and urban design.
