PIARC (World Road Association), founded in 1909 and comprising 125 member governments from all over the world, is the global forum for exchange of knowledge and experience on roads, road transport policies and practices. With consultative status to the Economic and Social Council of the United Nations, the Association is contributing to a stable and sustainable global development of the road and transport sector.

Technical Reports Road bridges

This page lists technical reports of PIARC in the field of road bridges. These publications are classified chronologically.

  • Adaptation of road bridges to climate change

    Climate change has now become a global issue of concern and it is for this reason that PIARC has incorporated it into the strategic themes and technical committees for the term 2012-2015. Higher levels of carbon dioxide as part of greenhouse gas emissions are being released resulting in heat being trapped in the atmosphere, which over time will result in a rise in the earth's air temperature. This rise in temperature will filter into the oceans, causing sea water to expand and therefore raise sea [...]

  • Risk-based management of the bridge stock

    In the past, the Technical Committee 4.3 Road bridges reviewed the bridge management systems implemented in several countries and advised a revision of the management of bridges based on risks (Management of bridge stock 2011 - report ISBN 2-84060-238-5). This report aims to provide some answers with respect to risk-based management for bridges. It discusses the integration of risk-based analyses into the bridge management systems of several countries and gives examples of formal methods of [...]

  • Estimation of load carrying capacity of bridges based on damage and deficiency

    Based on the answers from 18 road authorities in 16 countries this report examines the extent to which an estimation of the load bearing capacity of road bridges is made based on damage and deficiency. The report firstly examines the Codes/Directives/Manuals used for the estimation of the load carrying capacity of road bridges and what triggers the inspection procedures that lead to the estimation of the load carrying capacity. It then deals with the practice of road bridges inspections in different [...]

  • New repair and rehabilitation methods for road bridges

    In many countries, the average age of the road bridges stock is over fifty years, and a large number of the bridges are not in good condition. The economic issue leads to the search for innovative solutions to extend the service life of the bridges and rehabilitate them in the most cost-effective way. From an international survey, twenty-two cases of degradation were selected affecting mainly reinforced concrete and prestressed concrete bridges. For each of them, countries were invited to describe [...]

  • Road bridges improvement of durability in design and construction

    This 62-page report compiled by Technical Committee 4.4 has sought to pool the experience of the members ofthe committee in respect of current design and construction philosophy in identifying and responding to perceived durability problems of engineering structures. A questionnaire was formulated by this group for circulation to PIARC members. It was agreed to limit the scope of the enquiries to steel and concrete bridges of medium span (less than 150 meters individual span), as this represented [...]
