Road Bridges - New Rehabilitation Materials and Technologies - Technical Report

Every country around the world need to manage and to rehabilitate his bridge stock. The latter may be old (for example about 60 years or more in Europe) or very young (about 15 years for example in new high-income countries but not only). Therefore, the needs for rehabilitation of an aging bridge stock may be different from one country to the other. The aging of bridges is one of the main cause of rehabilitation, but not only. Extreme events related or not to climate change are also an important [...]

Advancement of Inspection Techniques / Technologies as a Part of Bridge Management Systems - Collection of Study Cases

Bridge inspections form an essential basis for the maintenance management of bridges and engineering structures. New technologies such as remote sensing and the use of a variety of sensors have the potential to significantly improve the quality of the results of structural inspections, but due to a lack of experience on the part of owners and operators they are not yet being used comprehensively. In order to make these technologies more readily available, Working Group 2 of the Technical Committee [...]

Bridge And Tunnel Strikes By Oversized Vehicles

This report details the findings of a study carried out by Roughan & O’Donovan Ltd. (ROD) under the supervision of PIARC, in response to an open call for proposals published by PIARC to conduct the “Bridges and tunnels strikes by oversize vehicles” Special Project. The objective of the study was to examine proven countermeasures, practices, and technologies used to reduce the incidence of oversize vehicles striking bridges and tunnels along with effective processes for accurately reporting [...]

Overweight Vehicles: Impact On Road Infrastructure And Safety

This report compiled the available information on overweight road freight vehicles around the world, the impacts they have on road infrastructure, road safety and the economic position of road infrastructure managers, and collected global best practices to prevent and mitigate overloading. Global experience Weight limits for road freight vehicles typically cover 2 aspects: gross vehicle weight and axle (set) load. Gross vehicle weights differ greatly between countries and continents, from as low [...]

Bridge Design Toward Improved Inspection And Maintenance - Technical Report

The principle of designing bridges while having in mind the future inspections and maintenance has often been overlooked in the past, when in the design stage greater emphasis was placed on firstly fulfilling just the "initial requirements" of the bridge – mainly structural safety and serviceability – and secondly minimizing the initial capital cost. This approach has, in many instances, resulted in costly future maintenance which far exceeded the initial capital savings of not considering the [...]
