  • Evaluation and funding of road maintenance in PIARC member countries

    This report presents an up to date description and analysis of the methodologies used by PIARC member countries and international agencies for evaluation and funding of road maintenance. The common problem of inadequate attention to road maintenance is highlighted. The concept of a systematic approach to managing the road network as an asset is described. The report mainly addresses the evaluation and funding portion of road asset management, setting out objectives for evaluating road maintenance. [...]

  • Planning and Programming of Maintenance Budgets

    Maintenance is essential to prevent the deterioration of asset value and ensure user safety. However, the budgets allocated for maintenance are often considered insufficient to keep the infrastructure at optimum levels. The reasons for this funding shortfall can be a lack of means within the road administration, but it can also be due to the poor justification of need to decision-makers. PIARC Committee C6 was asked to analyse, from a practical point of view, the options open to road administrations [...]

  • Whole-Life Costing of Roads - Concrete Roads

    In 1996, PIARC Technical Committee on Concrete Roads (C7) created a subcommittee on the theme "Whole Life Costing (WLC)". On the basis of a broad view over the subject, based on the existing WLC systems in Sweden and UK (COMPARE), two questionnaires were drawn and issued in 1997. The result of the questionnaires shows that many countries are very interested in this subject, and also that many countries use whole life costing as a basis for decisions about road design and guidelines for the national [...]

  • Economic Evaluation Methods for Road Projects in PIARC members countries

    PIARC Committee C9 on Economic and Financial Evaluation has prepared this report to present an up to date description and analysis of the methodologies used by PIARC member countries and international agencies for economic evaluation of road projects, the range and valuation of the impacts considered, and how the evaluations are accepted and used in decision making processes. The methodologies covered by this report are, in general, those used for evaluating capital investments at the project level. [...]
