Highway networks generally represent the largest asset of public infrastructure. Management of the performance of this asset through timely rehabilitation and/or maintenance is well understood, however, less is known about how to manage the value within the context of public-private partnerships or other delivery models. Asset valuation holds great promise as a readily understood (to the public and private sector) performance measure and, as an asset management integration mechanism for trade-off analysis between competing components (pavement, bridges etc.). However, there is no framework available to guide engineers in the selection of which valuation method to use for which asset category. Using the City of Edmonton pavement database as a case, the network asset valuation is calculated for five valuation methods to gain an understanding of the variation between methods and, as such, the impact of selecting one approach over another.
