Kerbs & Channels

Kerbs and channels form a barrier between road pavement and nature strips, which aim to:

  • Assist drainage

  • Improve channeling and delineation of traffic flows;

  • Protect pedestrians

  • Reduce maintenance of nature strips

  • Improve aesthetic values of road alignment.

Kerbed roads have a significant effect on driver behavior. Kerbing affects the distance that drivers align their vehicles from the edge of a road and acts as a physical and psychological barrier that discourages them from leaving the road surface. Generally lateral placement of vehicles varies with kerb height and steepness as well as the location of other obstructions outside the kerb-line. Kerbing improves delineation of road edges and contributes to the appearance and safety of the road.

The main purposes for kerb construction are:

  • To assist drainage.

  • To improve channelization and delineation of traffic flows.

  • To protect pedestrians.

  • Improvement of aesthetic values of the road alignment.

  • To reduce maintenance of shoulders.

  • To provide a boundary to landscaping treatments.

The use of kerbing to control vehicle movements is generally recommended in urban environments particularly at intersections because it is most effective at low speeds and small angles of impact.
