  • 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 [...]

    The objective of the Road Technology Topic Area set out in the 1995-1999 PIARC Strategic Plan is "to improve the provision, maintenance and performance of road infrastructure in accordance with international best practice". One of the essential requirements to meet this objective is a means of assessing the relative merits of the various forms of construction and of the maintenance processes. This can be done by considering the costs and the performance of the materials and processes used over an [...]

  • The Role of Economic and Socio-economic Models in Road Management

There is, therefore, a growing need for methods and tools to meet this requirement. The development of such tools implies a number of technical obstacles, including: [...]

  • Economic Evaluation Methods for Road Projects in PIARC Member Countries

It was conducted as a questionnaire survey of all member countries of C9 in 1997, supplemented with information from other available sources e.g. publications and reports.
