Launched in May 2022, the PERSEUS project focuses on creating innovative asphalt mixtures to reduce road traffic noise while incorporating recycled tire materials. The project, funded by CDTI, is led by CAMPEZO with contributions from ASFALTIA, MOEVE, and SIGNUS, and support from TECNALIA.

The initiative addresses the urgent need to mitigate road traffic noise in urban areas. A key innovation involves replacing aggregate particles (1-8 mm) with recycled rubber granules from end-of-life tires. This sustainable approach aims to significantly reduce road noise while ensuring pavement durability.

In November, a test section was successfully installed on the AP8 “Metropolitan Southern Bypass,” an area provided by the Bizkaia Provincial Council through the Bizkaia Connected Corridor (BCC) initiative. This platform enables real-world testing and validation of mobility and infrastructure technologies. Two rubber-based asphalt mixtures were applied and have shown promising results. Over the coming months, mechanical properties of the installed pavement will be analyzed, and noise tests will be conducted using specialized vehicles.

The findings will determine whether using larger rubber particles than those typically used in asphalt mixtures offers an efficient, sustainable solution for noise-reducing pavements. Such innovation could have a positive impact on reducing traffic noise and improving quality of life for nearby populations.
