Reduction of traffic noise has become an increasing priority in the environmental policy of European countries, not in the least by the European Noise Directive 2002/49/EC imposing to EU member states to produce noise maps and actions plans regarding road traffic noise. Improvement of human well being and reduction of noise related adverse health effects being an important motivation, it should be clear that traffic noise reduction represents an economical profit. The working group "Health and Socio-Economic Aspects" of the EU estimated the value of 1 dB(A) reduction of the outdoor Lden level to be 25 €/household/year1. Now, low noise pavement (LNP) applications represent the preferred solution to reduce traffic noise, especially in urban context, where it is generally the most cost-effective one. They have numerous advantages with respect to other noise abatement measures (like noise screens or façade insulation. Low noise pavements are a powerful tool in the abatement of traffic noise, but experiences with some types of LNP has not always led to satisfactory results. This has led to reluctance to use LNP, which is not always based on objective figures and facts.
