Towards an Indicator of the Health Condition of Bridges

The survey was carried out to clarify the present conditions and trends of the management of bridges currently in service by collecting knowledge and information on bridge management in various countries. The results of the survey can then be used to improve inspection and diagnosis techniques. The survey questionnaires were given to various countries, and seventeen countries responded (Austria, Denmark, Finland, France, Hungary, Italy, Japan, Netherlands, Norway, Poland, Portugal, Rumania, Slovakia, [...]

A Fact Finding Review of Performance Specifications in 2002

This document is an awareness-raising review of the current state of the art for performance specifications. It provides insight into three important areas of performance specification and presents the responses to an international questionnaire on the subject. The three important areas of discussion are appropriate definition; initial and whole life cost implications, and the use of warranty periods in the procurement contract.

Inventory of Surface Characteristics Measuring Equipment

In 1989, the PIARC Technical Committee C1 started compiling an inventory of surface characteristics measuring equipment used throughout the world. The result is a comprehensive listing of equipment for measuring longitudinal evenness, transverse profile distresses (rutting), texture and skid resistance (tire-pavement friction) of pavements, the deformation of road surfaces. The information is presented as tables (one table per device) which composed a bilingual catalogue (English - French). [...]

Urban Road Network Management

Many different organizations are interested in using the area above and below the streets. One of the most important things is to co-ordinate and harmonize the various areas of interest. The purpose of this report is to show who decides how the street zones in cities are used; to show different organizational solutions chosen to share access, and the type of laws that form the basis of this work; to define those who have an interest in using street zones and the conflicts that arise; to show the [...]

International Experiment to Compare and Harmonize Skid Resistance and Texture Measurements

This document presents the International Experiment involving 41 friction and texture measuring devices that operated on 58 locations (including 10 airfield runways) in Spain and Belgium in September-October 1992. The analysis of the results and conclusions bear on correlations between texture measuring devices and friction measuring devices; relationships between friction and texture according to different models; repeatability of each device; reproductibility between devices and a proposal [...]
