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 for each of the above mentioned issues. Each chapter is divided into three parts: definition of the problem, approach to the problem per country, available information per country.
