Noise monitoring within LIFE NEREiDE: methods and results

LIFE NEREiDE is an EU funded Project (LIFE15/ENV/IT/000268) aiming to the implementation of new low noise surfaces made of recycled materials as rubber from end of life tyres (ELTs) and recycled asphalts (RAP). The objective is to mitigate noise exposure with green technologies achieving better acoustical, psichoacoustical and safety properties. This paper is focused on reporting results of the comparison of ante and post operam noise measurement campaign carried out within the first implementation site on the different stretches of implementation of new pavements and to show pro and cons of selected indicators and measurement protocols. Results are reported according to different parameters: CPX values, environmental noise values at roadside and SPB values with a new method for urban pass by. In fact, a side objective is to establish methods to evaluate pavements efficiency with methods that can be easily implemented in urban contexts, avoiding long manned measurements. The results highlight benefits of innovative pavements compared to reference coeval ones and pointed out the effects on light vehicles noisiness.
