Economic Evaluation of Long-Life Pavements

Phase I

This study on the Economic Evaluation of Long-life Pavements – Phase I was carried
out by an OECD Working Group under the RTR Programme 2001-03. The report
explores the economic case and technical prospects for the development and use of longlife
wearing courses for the pavements of highly trafficked roads. It draws conclusions,
based on economic analysis, on the circumstances under which long-life wearing courses
that involve a higher initial construction cost may be economically viable. It also
identifies the material properties and performance likely to be needed as well as classes of
possible candidate wearing course materials.
