Kerbing and Edge Details

Kerbing and edge details define the boundaries of the carriageway, providing structural support, drainage control, and safety for road users.

Kerbs are typically made of concrete or stone and serve multiple functions, including separating the carriageway from footpaths or verges, containing the road pavement, and guiding surface water to drainage points. Different types of kerbs are used depending on their purpose, such as barrier kerbs for pedestrian protection or flush kerbs for cycleways. Edge details also include the design of verges and hard shoulders, which contribute to the overall safety and functionality of the road.
