Abstract [en]
The application of reclaimed asphalt is becoming increasingly important in the European Road Network. The demand for more environmentally friendly methods to construct pavements is growing constantly. Most developed countries are seeking new ways to consume less energy and virgin materials and produce less CO2-emissions and less waste. Beside the conventional recycling options (i.e. hot asphalt mixtures), cold recycling is becoming more popular and have been successfully applied in numerous road structures. However, the guidelines on when and how cold recycling can and should be applied differ from country to country. Structural design and mix design are also different in the European countries. A comparison of the use of cold recycling in road construction indicates that some countries are ahead of others and that comparing methods and approaches could be beneficial for all. In this paper, experiences and results are compared from five European countries. Each country presents 2-4 road sections where cold recycled materials are included in the asphalt base layer and where test results are available. Structural design, mix design, traffic loads and test results are compared to assess the success each road and study what could be learned for future constructions.
