Resumen
A research and development project named ‘environmentally friendly pavements’ is being conducted under the auspices of the Norwegian Public Roads Administration and in close cooperation with research institutions and the road industry. The project focuses on the noise and dust properties of road surfaces. The project was started in 2004 to be completed in 2008. The project aims to optimize the environmental properties of road surfaces and thereby contribute to achieving the national targets set for levels of noise and suspended matter (road dust). A central part of the project is the development of low noise asphalt surfacing adapted to Norwegian conditions. Under the project, a wide range of test pavements have been constructed and are being monitored. The effect of reduced maximum aggregate size in ordinary pavements is investigated. Further two sections with one layer porous pavements and three sections with twin layer porous pavements have been constructed. Different types of thin layer pavements are also being tested. Description of selected test pavements and results from field measurements is presented in this paper.
