As this indicative graph illustrates, if road administrations base their decisions only on minimising direct road administration costs, they would be likely to undertake road maintenance at times which impose higher costs on road users and result in less than optimal total project costs. 1.

Traffic growth rate: 1 or 2% pa. The economic analysis undertaken in Phase I showed that in certain circumstances there could be considerable economic benefit in developing new long life pavement wearing courses with the LONG LIFE SURFACES FOR BUSY ROADS – ISBN 978-92-821-0158-2 - © OECD/ITF, 2008 34 – KEY FINDINGS OF PHASE I STUDY appropriate performance characteristics. The detailed findings included in the Executive Summary of the Phase I report were as follows1: “From a cost viewpoint, long-life pavement surfacing costing around three times that of traditional wearing courses would be economically feasible for a range of high-traffic roads.
