Welcome on piarc.org!

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.

  • International climate change adaptation framework for road infrastructure

    Actions undertaken to mitigate the negative effects of climate change on road networks have varied from one country to another. They include legal, regulatory and institutional measures; promoting other transport modes; introducing new, green technologies; undertaking permanent supervision of embankments and slopes to reduce risks of collapse, accidents and interruptions of service, as well as developing new methodologies and analytical tools to identify, assess and mitigate risks and thus reduce [...]

  • Road transport system and environment preservation - Review of national policies

    Climate change is one of the most serious threats facing the world today. There is compelling scientific evidence that the global climate is changing and the primary cause is the release of greenhouse gases resulting from human activity. Many governments are putting in place legislative and policy frameworks at a national level to address climate change. Whilst transport is a key driver of the economy, it is also a significant and growing contributor to greenhouse gas emissions. Recognizing that [...]

  • Alternative solutions for fossil fuels for the road system

    The report looks at the technologies available to generate energy in the highway context and also qualitatively assesses the opportunity to reduce the energy used by existing highways infrastructure. Case studies related to some potential technologies and techniques are presented: thermal collection, photovoltaic collection, wind microgeneration, water microgeneration, efficient use of new materials. There exists a variety of different ways in which energy can be generated by innovative use [...]

  • Innovative approaches towards the use of locally available natural marginal materials

    The utilization of materials locally available on the site of a road project is a major concern in the context of sustainable development and perfectly meets the socioeconomic and environmental criteria involved in it. The report is based on the answers received from twenty-two countries. Five different families of locally available marginal natural materials have been identified. Information on placing and processing is given for each country. A comparison is also made of classifications and [...]

  • Vulnerability of Geotechnical Infrastructure to Climate Change and Adjustment Measures According to the Geographical Context

    The report identifies foreseeable damage and the measures to be taken in a geographical context where climatology and geomorphology are aggregated. Five climate trends are covered: increase of average temperatures; decrease of average precipitation; increase of winter precipitation; increased intensity of extreme precipitation; and increased storm severity. These five trends result in thirteen induced general phenomena, to which nine types of road damage are linked. The geomorphology approach [...]
