Styrene–Butadiene Rubber (SBR), the predominant polymer in tire tread formulations, is directly responsible for the acoustic and tribological response observed during contact with concrete. As a viscoelastic polymer, SBR undergoes deformation, adhesion, and friction processes that not only govern wear and particle release but also generate a characteristic acoustic field during rolling. The analysis of these polymer-driven acoustic emissions offers an indirect pathway to monitor the state of the material, providing valuable information on how the molecular structure, viscoelasticity, and surface interactions of SBR influence both wear mechanisms and environmental release of polymeric residues.

An experimental test bench was developed, consisting of a rotating concrete drum in contact with a tire segment, subjected to controlled load, speed, and inflation pressure. The setup integrates vibration sensors and a high-precision acoustic acquisition system with sound level meters, enabling synchronized recording of rubber–concrete interactions and their associated noise emissions under reproducible conditions. The recorded signals were analyzed using Fast Fourier Transform (FFT), Short-Time Fourier Transform (STFT), and one-third octave band analysis to identify dominant frequencies, harmonics linked to tread patterns, and resonances associated with concrete texture at rolling speeds of 20, 25, and 30 km/h. Preliminary observations indicate that acoustic spectral features can reveal relevant trends in the dynamic response of SBR, suggesting their potential as complementary indicators for assessing polymer wear mechanisms and material performance during tire–pavement interaction.
