Are kerbs necessary in road pavements?

In general, kerbs are essential in road pavements due to the following reasons (based on Arthur Wignall, Peter S. Kendrick and Roy Ancil):

(i) They provide strength to the sides of road pavements and avoid lateral displacement of carriageway due to traffic loads.

(ii) In terms of road safety, they serve as a separation line between footway and carriageway and aid car drivers in driving safely.


(iii) They act as a vertical barrier to guide the surface runoff collected in road pavements to the gullies.

Thanks for the information on whether or not kerbs are necessary. I agree that kerbs are necessary for safety and for the added strength to the side of road pavement. I would imagine that having to make a kerb for all of the roads that are made isn’t an easy or cheap job, but I am sure that it really pays off in the end as far as safety and quality goes.
