Noise reducing asphalt stops noise at its source and saves money

Lower roadside noise levels of asphalt wearing course can save money in reducing or avoiding indirect noise reducing systems such as sound barriers, special windows or any other noise protection system. Noise reducing asphalts such as Porous Asphalts significantly limits the emergence of noise directly at its source in the tyre-surface interaction.
