About this video-
Dosto is video me app logo ko kerb ke bare me bolunga.
Kerbs indicate the boundary between the carriage way and the shoulder or islands or footpaths. Different types
of kerbs are (Figure 12:3):
• Low or mountable kerbs : This type of kerbs are provided such that they encourage the traffic to remain
in the through traffic lanes and also allow the driver to enter the shoulder area with little difficulty. The
height of this kerb is about 10 cm above the pavement edge with a slope which allows the vehicle to climb
easily. This is usually provided at medians and channelization schemes and also helps in longitudinal
drainage.
• Semi-barrier type kerbs : When the pedestrian traffic is high, these kerbs are provided. Their height is 15
cm above the pavement edge. This type of kerb prevents encroachment of parking vehicles, but at acute
emergency it is possible to drive over this kerb with some difficulty.
• Barrier type kerbs : They are designed to discourage vehicles from leaving the pavement. They are
provided when there is considerable amount of pedestrian traffic. They are placed at a height of 20 cm
above the pavement edge with a steep batter.
Submerged kerbs : They are used in rural roads. The kerbs are provided at pavement edges between the
pavement edge and shoulders. They provide lateral confinement and stability to the pavement.
