The term quiet pavement or quieter pavement is used for pavements where the noise levels from tire/pavement interaction are reduced in comparison with traditional pavements. Noise reduction is usually achieved by controlling the texture of the pavement surface to absorb some of the noise produced by moving vehicles.
Why use this strategy?
Noise pollution is a significant problem in residential areas and many public agencies have criteria for mandating noise mitigation measures such as sound walls when noise levels raise above a certain threshold. Using a quieter pavement surface can reduce noise levels by 3-5 decibels (dB) which translates into 50% reduction in noise energy or the equivalent of doubling the distance between the source of the noise and the receptor.
How to use it?
Consider diamond grinding for concrete pavements. Consider using rubberized asphalt concrete, open graded friction course, or stone matrix asphalt.
