  • Social and environmental approaches to sustainable transport infrastructures

    Based on a survey performed in different countries facing various economic development contexts and on case studies, this report studies: how is sustainable development dealt with in politics, planning, strategy and operation; what are the methods, targets and criteria used to assess sustainability; which social and environmental impacts are particularly paid attention to, in particular as regards natural and human habitat fragmentation; How environmental issues are included in road [...]

  • Evaluation and Limitation of Impacts social and environmental for Road Networks and Transport Policies

    One work area of the PIARC Committee 14 on "Sustainable development and Road Transport" concerns the evaluation and limitation of impacts of road networks and transport policies. The Road is life (Via Vita). This are the words contained in the logo of the World Road Association established in 1909. With this as their moto, most developed countries, and more precisely the engineers have through the years provided for the design, construction, maintenance, management and operation of roads. The primary [...]

  • Road Tunnels: Vehicle Emissions and Air Demand for Ventilation

    In 1990 and 1995 PIARC published the calculation methodology and the emission factors for road tunnel ventilation design. An update of the existing PIARC methodology was necessary, as the emission standards of the vehicles were becoming more stringent and hence the vehicles cleaner. The old version described the emission situation up to the year 1995. This document has been produced by working group 2 of the PIARC Technical Committee on Road Tunnel Operations in the framework of its activities between [...]

  • CD-7802 - Pavement Recycling (Guidelines)

    This document, realised by the PIARC Technical Committee on Road Pavements (C7/8), is avaible only on CD-ROM. It contains three different guidelines: cold in place recycling of pavements with cement, cold in place recycling of pavements with bitumen emulsion or foamed bitumen, and hot mix asphalt recycling in plant. After a general introduction the three techniques will be discussed. This document is not intended as a specification document or to be a state of the art report. Its [...]

  • Environment and Construction of Road Projects

    One work area of the PIARC Committee on the Environment concerns the consequences of the construction of road projects. In July 1997, an inquiry was sent to all PIARC member countries. It dealt with the five major topics identified by the Working Group: soil and water protection; how to deal with contaminated land; recycling of used materials; how to take account of flora, fauna, archaeology, water and noise; work sites. This report contains the answers from twenty respondents and provides recommendations [...]
