Highway Inspection
Once the quantity of the asset has been established through inventory collection a maintenance strategy is determined by first establishing a regime of inspections.
By setting a frequency of inspection with regard to the road network hierarchy, associated condition factors can be risk assessed. This allows programmes for maintenance to be developed and forms part of an authority's Highway Asset Management Plan (HAMP).
Inspection type and frequency should be an integral part of an authority's network maintenance policy and address the core objectives of:
Safety; the compliance with statutory obligations and whether the network condition is meeting the users' need for safety.
Serviceability; network reliability, availability and integrity and the ability of the network to meet the needs of users
Sustainability; formulating procedures which minimise cost over time and maximise the contribution to the community.
