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

  • Inspections and Damage Assessment Techniques - Case Studies

    The PIARC TC D.3 Bridges Technical Committee is publishing a worldwide compilation of case studies as examples for bridge owners in making critical decisions to ensure the safety of the traveling public during a bridge incident caused by damage and deterioration. This case study compilation has 28 worldwide case studies received from 15 unique countries. These case studies provide examples of incidents where owners discovered damage or deterioration under two main circumstances. Firstly, damage [...]

  • 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 [...]
