Summary

From Western Europe to Russia, the constant ageing of bridges and network structures becomes, forty years after a global construction boom, one of the most preoccupying matters for countries and regions where transportation and communication are a real economical challenge. The proper addressing of budgets for such an issue requires a sturdy technical approach, as well as a proven cost effective methodology: Where to start? How much to address? What are the appropriate tools? How to monitor the results and control efficiency?
The Road Administration of Bulgaria and Advitam set up jointly, in 2003, a national scale solution to all these
questions. Rehabilitation is not a matter of deciding how much money to deploy, but shall / can fit to available budgets. The project mainly stands on three steps:
A global audit including regulations in effect as well as the infrastructure network. Practical methods and techniques allowing it within limited time and controlled budget from the beginning
A global infrastructure network evaluation, using objective indicators through synthesis tools
The setting and application of a progressive director scheme, from partial rehabilitation projects towards a global preventive maintenance management.
Using modern computerized tools and methodologies, the Road Administration handled its network globally and has now significantly increased the mean technical and service level of all 4 000 bridges of the country. With controlled financial means, the global preventive infrastructure management is now and only one step further. The purpose of this article is to describe in detail the means that have been deployed in 2003, as well as the results of the project.
