Climate Change, Other Hazards and Resilience of Road Networks

This report contains a collection of case studies related to climate change, other hazards and resilience of road networks. It comprises an introduction, outlining the work program for Technical Committee (TC) 1.4 Climate Change and Resilience of Road Networks, and objectives of two Working Groups within the Technical Committee. These are Working Group 1, which aims to identify uniform and methodological approaches to increasing resilience of roads. It covers hazards and environmental threats within [...]

Carbon Neutrality of The Road Sector

Road transport is vital for society to function and, for the foreseeable future, is expected to remain the dominant mode of transport for people and goods. However, the construction, operation, maintenance and use of the highway infrastructure are responsible for large quantities of carbon emissions. Knowledge of the non-reversible, damaging consequences of climate change has resulted in global acceptance of the need to reduce carbon emissions in all sectors of human activity, including the highways [...]

Measures for Increasing the Adaptability of Road Bridges to Climate Change

The IPCC (Intergovernmental Panel on Climate Change) Working Group 2 report states that changes in climate have caused impacts on natural and human systems on all continents and across the oceans. Key risks from climate change are typically defined as warming trend, extreme temperature, precipitation, extreme precipitation, drying trend, and sea level rise. The impacts of climate change will be regional and depend on the level of adaptation and mitigation achievable. Transportation infrastructure [...]

Preserve Earthworks and Rural Roads from the Impact of Climate Changes

This report puts together good practices on the various regional approaches to the impacts of climate change on roads and little hydraulic works. The subject has already been addressed during previous PIARC cycles but more on the general geotechnical aspect. It includes the definition of the climatic parameters that had to be taken into account, the definition of a rural roads and the terminology of the structure of a road (going from embankments, slopes to the pavement layers). The report covers: [...]

Traffic Noise – Best Practice Guide

In recent years, knowledge about the health effects of traffic noise has grown substantially. Many studies have found that long-term exposure to traffic noise is associated with various health impacts such as sleep disturbance, cardiovascular disease and depression. While there remain knowledge gaps concerning the risk for particular noise profiles, there is sufficient evidence to suggest that a large proportion of people living within major urban centres is at risk due to excessive noise level [...]
