Current trends and future perspectives of quiet pavement technologies for urban noise island mitigation: a review

Vehicle traffic is the primary noise source in urban areas, mainly generated by tire-pavement interaction, vehicle propulsion, and air turbulence. Tire-pavement noise stems from tire pattern, sliding of tire, pavement roughness, and air-pumping, influenced by tread impact and other mechanisms. Amplification factors like horn and resonance effects amplify this noise: surface characteristics like porosity, texture, and mechanical impedance play a crucial role. For asphalt pavements, noise reduction can be achieved through different construction technologies such as porous, textured, and poroelastic pavements. For rigid pavements, adjustments to porosity and surface texture exhibit notable noise reduction capabilities. Despite the higher initial implementation costs, case studies highlight long-term societal benefits, contributing to sustainable, quieter environments. This paper provides a narrative account of the tire-pavement noise generation, amplification, and reduction mechanisms, as well as examines the different quiet pavement technologies for asphalt and concrete pavements. Furthermore, the scope for further research is also discussed.
