In general, kerbs are essential in road pavements due to the following reasons
(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.
